[A/N: I don't own Percy Jackson and the Olympians and any of the characters. I'm a huge fan of Percabeth and I decided to write my own story of them. Though I made some changes, I'll keep this story as faithful as I can. One of these changes is that Percy and Annabeth had been dating for four months before Percy disappeared. I decided to extend their time together. This took place between The Last Olympian and The Lost Hero.

Go easy on me with your comments, this is my first story. Hope you like it. :D ]

WISE GIRL'S SEAWEED BRAIN

Chapter 1: Kiss and Make-up

PERCY

I fumbled stupidly with the bluish-green tie wrapped on my neck, having no clue how in Hades I'm supposed to tie it properly. I was resolved not to ask for Mom's or Paul's help but one glance at my wrist watch sent me into a state of panic. I only have fifteen minutes left before I have to meet Annabeth at her apartment.

Oh, yeah. Annabeth Chase, daughter of Athena, architect of Olympus and an honor student, is my girlfriend. We've been together for almost four months and in a week's time, we would be celebrating our four-month anniversary. But since winter break's already here, we decided to spend the vacation at Camp. But because I was being an "ideal" boyfriend, I made a reservation – with Paul's help – at a local restaurant just so Annabeth and I can have an early date.

I sighed and went out of my room and went searching for Mom. "Mom?"

"Yeah, Percy?" I followed the sound of her voice and found her at the kitchen. "What's up, honey?"

"Can you . . . um, help me?" I asked, motioning to my tie.

She smiled and went over to me. In a matter of seconds, she had the stupid thing done.

"I guess I have to go. Annabeth will be pissed if I keep her waiting."

Mom smiled. "Enjoy your night," she said. "And remember not to stay out too late; you haven't packed your things yet." I nod. "And remember to behave, okay?"

She had a mischievous glint in her eyes. I had to think hard for some time before I got what she meant. Hey, call me slow. Annabeth didn't start calling me Seaweed Brain for nothing.

"Uh, Mom," I groaned. "Seriously?"

She laughed. "I'm just kidding. Go on. It's rude for a girl to wait for her date."

I gave a nervous chuckle. "Yeah. I'll see you later." I kissed her cheek and went down to my car – a silver Corvette Stingray, a gift from my Dad, Poseidon, for my sixteenth birthday. Well actually, it was from the Olympians as a token of thanks for saving them last summer. Along came a note that I knew was written by Mr. D, or Dionysus, our camp director. I knew it for a fact because he stubbornly got my name wrong.

Peter Johnson,

A gift from the Almighty Olympians. Happy birthday. Hopefully this will be your last.

The ever awesome,

Mr. D (Dionysus)

Annabeth had been living in Manhattan for the past four months, for two reasons; first: she needed to be as close to Empire State Building, the entrance to Mt. Olympus, as possible and second: me. Yeah. She didn't say that but hey, I knew I'm the other reason. She just wouldn't say it.

Annabeth's apartment wasn't that far from mine. I barely had time to let my nerves get in the way before I saw her opening her door and looking around. Just in time. She gave me a brilliant smile. After all this time we're together, I still haven't gotten used to her beauty. [Melodramatic, Percy.] The way she looked tonight didn't exactly help me in easing down. She was wearing a green dress that hugged her slender figure; her hair was pulled up and rained down on her neck in curls; she was wearing her owl earrings and had traded her camp necklace for a string of blue pearls – a gift from mine for our second month anniversary.

I smoothened out the wrinkles on my shirt and pants and got out.

"Hey," she said, kissing me. I took a step back when I saw her Dad and stepmom looking at us. Annabeth smiled. "Don't mind them, Seaweed Brain. Come on."

"I'll get her home on time, sir," I said. Mr. Chase nodded and closed the door.

When we were back at my car, Annabeth took my hand and squeezed it. I couldn't help but smile. Between the two of us, she was more expressive with her feelings. I tried from time to time but I always end up annoying her.

"So," she said, rubbing circles on my knuckles. "Where are we going?"

"Just wait," I said.

We talked about her time redesigning Olympus, Camp and what we were going to do this winter break. It wasn't long before I parked the car and looked at her. "Here we are," I announced.

"I kind of figured that out by myself," she said, smiling.

I couldn't stop it; I took her face between my hands and kissed her. She was caught off guard but kissed me back immediately. We pulled apart when we're both panting, grinning from ear to ear.

"What was that for?" she asked.

"I just missed you," I said truthfully.

She glared at me. "What is it this time, Seaweed Brain? What have you done?"

"Nothing!" I protested. Annabeth eyed me quizzically. She knew me too well to buy it. "Well, um, I'm not taking you to Paris or anywhere romantic today, just here in New York. I'm hoping to make up to it by my sheer awesomeness and –"

Annabeth stopped me with a kiss. I kissed her back reluctantly at first and eventually, just like before, we nearly lost control. We pulled apart at the same time. "I don't care if we have our date at your apartment, as long as I'm with you."

I grinned. "Why is that? Because you love me?"

Annabeth playfully slapped me and said, "Keep it up and I might gut you." She reached out and wiped something from my lips. "You have lipstick on you," she said and we shared a laugh.

"Your fault," I said as I opened the door to her side.

Annabeth took my arm as I lead her to the restaurant. It was nothing special, really, just a small building, but the ambience was cozy and romantic. Three violin players were standing up front, welcoming guests with "ear-soothing music." (Mom's description, not mine.)

A smiling waitress met us as we were climbing the steps. "Good evening, Ma'am, Sir. Do you have any reservation?" she asked.

"Yes, we do," I said.

"Name please?"

"Percy Jackson," I informed her.

She nodded. "Right this way, please." We followed her as she led us to the exit. Annabeth seemed surprise by this. Heck, why would you leave right after you arrived, right? I gave her hand a squeeze and I felt her clamp on mine when she saw the table set for two outside.

Now listen here, Annabeth only expected the best from me. Every time we celebrate our monthly anniversary, she would only go easy on me if I surprise her. For our first, I took her to Paris, with the help of Hermes, after retrieving his staff from the tiny giant Cacus. For our second, I took her to my Dad's palace under the sea and gave her a necklace. For the third, I took her back to camp for the weekend and decorated her bunk with flowers (thanks to the Demeter cabin).

And on our fourth, we're here.

It wasn't exactly unique or new but at least Annabeth seemed to like it. "Oh, Perce," she breathed. "This is beautiful."

I straightened when I heard that. "What did you call me?" I ask.

Annabeth laughed. "Why? Don't you like it?" she asked. "I could go back to using my more endearing pet name for you, Sea—"

"No," I said quickly. "Perce is fine."

Our servant left right after we were seated to get our food. I, Perseus Jackson, actually was one step ahead of my girlfriend, and ordered her favorite food. While waiting for the food, she took my hand and smiled at me. "This is amazing," she said.

"Only the best for you, remember?" I asked.

"You never fail to amaze me," she said with a note of disbelief.

"Hey," I protested. "I constantly get ideas sometimes, you know. And most of the time they concern you."

We were interrupted with loud noise coming from the inside. I glanced and saw a group of teenagers eating at a huge table, shouting, whistling and laughing loudly and generally ruining my moment.

Our servant came back with our food. "I apologize for our other customers," she said, setting down the plates on our table. "But, as my boss said, they are our loyal patrons and give good tips so we just have to put up with them."

"Yeah," I agreed.

"Enjoy your night, Mr. Jackson," she said before leaving.

Annabeth raised her eyebrows at me and followed the servant with her gaze. "What?" I asked her.

She shrugged. "Nothing."

We ate. The food was good – oh wait, Annabeth once told me that any food is good to me, as long as it's not spoiled or anything. Soon enough we were done and she reached across the table and took my hand again. "You're spoiling me, Seaweed Brain," she said.

I pretended to groan. "Can we go back to Perce?" I ask. "I really like it hearing from you."

"No, Seaweed Brain," said Annabeth, smiling. "But hey, feel free to start thinking for a new way of celebration for our fifth month anniversary."

My heart thumped. "Gee, thanks," I said sarcastically. "Now I have a month to worry."

She smiled at that one and it was easy for us to talk about random stuffs. I asked her how she was doing with redesigning Olympus – a fatal mistake. Annabeth launched into talking to me about gilded porticos, marble pillars, painted statues of the Olympians and so so. She must've noticed I wasn't paying much attention – honestly, I tried to, except my head hurt trying to understand what she was saying – for she pinched my palm.

"You're not paying attention," she said.

Busted. "Sorry. I just got distracted with your eyes." Annabeth blushed and I stifled a chuckle. I checked my watch. "Do you mind if we go to the park and hang out?" I asked. "This place is really loud."

Ananbeth looked behind me and I followed her gaze. The group of teenagers was still noisy. One was standing up, blushing and looking at our table. She was shaking her head while her friends were urging her onto doing something.

Annabeth looked back at me. "Sure."

We stood up and were about to go back to the parking lot when the girl I saw blushing earlier stepped into our way. I looked at her questioningly. "Hi," she greeted.

"Hello," Annabeth said reluctantly.

"Hi," I said.

"So," she murmured, her face still quite red. "I was dared to do this and I apologize in advance."

"What do you –" I didn't get the chance to finish. The girl pulled my tie down and kissed me hard on the mouth. I was too surprised to move. I felt Annabeth stiffen beside me as the girl's friends whistled and cheered at her.

She was suddenly yanked away from me as Annabeth glared at her. "What in Hades are you doing kissing my boyfriend?" she hissed.

"I told you, it was just a dare. It doesn't mean anything—"

"Well it does to me," Annabeth nearly yelled.

I stepped between her and the girl, ready to break a fight. "Annabeth—"

"And you!" she said, glaring at me. "Why didn't you stop her?"

"What? I was shocked! I didn't know what to do!"

"When a girl who isn't your girlfriend kisses you right in front of the girl who is actually your girlfriend, you push her away, not enjoy the kiss!" Annabeth stormed out of the restaurant, other customers looking at her retreating back.

"Annabeth!" I yelled as I ran after her. "Annabeth, wait!" She stopped beside my car and wouldn't look at me. "Look, I'm sorry—"

"Just take me home, Percy," she said, her voice shaking. I felt bad. I wanted to put my arms around her but I knew that would only piss her further more and I didn't want her to stab me with her dagger.

I sighed. "Okay." I opened the door for her and she got in. I circled around the car and stepped inside the driver's side.

I tried to talk to Annabeth during the whole time but she wouldn't pay attention. I tired taking her hand but she brushed mine off. I didn't expect our night to be ruined by a girl who kisses a guy without his permission.

As I pulled in front of their house, Annabeth grabbed the door but I was faster than her. I stopped her from getting out and forced her to look at me. I felt like someone was squeezing my hearth when I saw her tearing eyes. "Gods, Annabeth. I'm so sorry."

"Just let me go, Seaweed Brain," she said.

I exhaled deeply and removed my hand from the door. I got out after her as she ran to the door, slamming it to my face. "I'm really sorry," I whispered to the door. Thankfully, it didn't answer.

Feeling like a jerk, I drove back to our apartment. Lucky me, both Paul and my Mom were watching television at the living room. For me to get to my room, I'd have to pass them. They would see I was upset.

They turned around when they heard the door open, both of them smiling. "How was it, Per – " Mom stopped when she saw my face. "Oh, what happened?" she asked.

"Nothing. I'm going to bed."

After undressing, I jumped into bed, thinking of a possible way to make it up to Annabeth, but my train of thoughts got constantly interrupted by the sight of Annabeth crying. I would gladly take any poison, or injury, or take another bath at the River Styx, rather than see her crying again. My chest felt heavy and I was feeling awful.

A knock on my door made me sit up. Mom peeked in and let herself in, followed by Paul. "Honey, what happened?" she asked.

I shook my head. "It was nothing."

She and Paul sat down on either side of me. Paul placed a hand on my shoulder and said, "I understand if you're upset but keeping this to yourself will only make it worse. You know you can open up to us, right?"

I nod.

"So what is it?"

I tried to find the words. "It was just . . . a stupid kiss."

"You kissed her and she got mad at you?" Mom asked, undoubtedly confused.

"No. Someone kissed me in front of her and Annabeth got mad," I explained.

"Oh," said Paul. "Do you know the girl?"

"No."

"Then why did she kiss you?"

"It was a stupid truth or dare." I looked at him. There are times I find it easier to talk to Paul, rather than my Mom. Times like this. Paul was such a great guy. "What should I do?"

"Have you apologized to her?"

I nodded. "But she wouldn't pay attention to me." I sighed. "Gods, I don't want this winter break spent with the two of us fighting like this."

Paul placed a hand on my shoulder. "Percy, I may not be your real father but if there's one thing I know about you, it's that you will do the right thing. You and Annabeth had been through a lot. This is just a misunderstanding. Tomorrow, when you're at Camp, do something to show her how sorry you are."

"How?"

Paul smiled. "You'll know."

Mom ruffled my hair playfully. "I've said this before, honey, but your heart is always at the right place. You will do what's right for you and Annabeth. I have faith in you."

Those made me feel a little better. "Thanks, Mom." I turned to my stepdad. "And you, too, Paul."

They smiled at me. "Anytime." They stood up and bid me goodnight. I didn't know how long I stayed up. All I was aware of was that tomorrow, I'd do everything I have to for Annabeth to forgive me.

I was up the next morning to pack up my things.

Annabeth and I agreed to go to Camp together with Paul driving us. I was excited but because of our fight last night, the idea of being with Annabeth in a car made me nervous.

After wolfing down half a dozen of ham sandwiches – I could still eat like a starving person despite of the situation; it's a skill of mine – I went down to load my bag at Paul's car. I was closing down trunk when Paul and Mom went down, holding hands.

"Good morning, honey," said Mom.

"'Morning, Percy," Paul greeted.

"Hey," I said back.

"Ready?" Paul asked.

"Yeah."

Paul got in the car while Mom pulled Mom aside. "Percy," she said. "You and Annabeth are a new couple. You will experience fights much worse than this. Fights that might make you think that it's over with the two of you but you have to promise me one thing, Percy. I've seen how you act around her. I know how happy she makes you. Promise me you will never give up on her, okay?"

I chuckled. "Gods, Mom. I faced Kronos so I guess I have enough courage for Annabeth and I to pull through. I just have to find the right way to say I'm sorry to her."

"I'm sure you'll know," said Mom, pushing me to the car. "Now go ahead and get your girl. Don't take a no for an answer."

"You got it," I murmured as I jumped in.

Annabeth was sitting on their porch when we arrived. I went out of the car and helped her load her bags in the car. I sat beside her at the backseat and tried, unsuccessfully, to start a conversation. So we drove in silence.

Snow wasn't falling hard but the road was slick and slippery. Luckily, Paul was a skilled river so we were safe with him. As soon as I saw Half-Blood Hill from a distance, I felt excitement coursing through my veins. I missed Camp terribly. I couldn't wait to start planning with the Stoll brothers on pranking the other counselors, or eat barbecue with the campers, or play capture the flag with my friends.

Paul helped us with our bags and even came with us up to magical boundaries. Mortals couldn't enter and there's Peleus the dragon guarding the Fleece so it wasn't a good idea for my stepdad to come anywhere near him.

"Here," Paul said, handing me my bag. "Enjoy winter break, Percy. You, too, Annabeth."

"Thanks, Paul."

"Thank you, Mr. Blofis," said Annabeth.

Paul grinned at us and left. I took Annabeth's bag and carried it. We were greeted with the strawberry fields, the ampitheater, the Mess hall, the Big House and the Arena. "Imissed this place," I murmured.

Annabeth nodded. I sighed. Looked like apologizing wouldn't be a very easy task.

She started heading down the hill and to Cabin Six, the Athena Cabin. Inside, I could see her other siblings – Malcolm, Albert, Marie, and Isaac – all brainiacs like Annabeth.

I put her bag down at the foot of her bed. Annabeth headed to the bathroom without acknowledging my presence. I gave another sigh.

"Dude, what was that?"

I turned to see the whole Athena Cabin looking at me. Malcolm was the one who asked the question. I shrugged. "Just a little misunderstanding."

"Did you do something to her?" asked a small voice. I craned my neck to see who said that and saw a boy with the trademark of stormy gray eyes of Athena's children and distracted expression looking at me. He was a new camper, probably six or seven. I believe his name was Elliot.

"I guess," I admitted. The kid glared at me. I held my hand sup and said, "It was unintentional."

"Make sure to fix it or I'm going to feed you to Peleus," he threatened me.

I couldn't help but laugh. "You got it, kid." I went out of the Cabin before any of them got the idea that feeding me to the dragon is a spectacular one.

Suddenly, an idea fell into my mind, something inspired by what Mom said. I smiled to myself and went to find Will Solace and Katie Gardner.

ANNABETH

I wasn't aware I had been staring at the same page of the book I was reading for the past half-hour until Malcolm, my half-brother and second in command, spoke to me.

"You're going to burn a hole on that book, Annabeth," he said. I looked up and saw some of my siblings staring at me. "And enough of the scowling; it doesn't suit you."

I exhaled and put my book down. What I saw last night really hurt me. I had the right to be, Percy's my boyfriend. If someone can kiss him, it's going to be me. "I didn't realize," I said.

Malcolm eyed me. "Something wrong with you and Percy?" There's no point in not telling the truth. Lying to an offspring of Athena? Good luck. So I nodded. "I figured as much. He seemed pretty upset. What happened?" he asked, then quickly added, "If you don't mind my asking."

I sighed. My siblings knew everything about me but I tried to keep my relationship with Percy as private as we could, which was next to impossible since we're the "power couple," as Drew put it.

"It's nothing. It would be fixed soon, I promise."

Malcolm nodded. Then Elliot, the newest addition to our little family, walked up to my bunk and said, "If he hurt you again, I will cause him some serious pain."

I laughed and ruffled his hair. I heard the conch shell blowing from the distance and I checked my watch. Almost dinner. How did time pass so quickly? I'd been to absorbed with the burning image of that stupid mortal girl kissing Percy that I didn't notice time passing.

I stood up and announced, "Come on, everyone. Time for dinner. Line up and head to our table and no, Elliot, no cutting the line. Stay at your place."

As we headed to the dining hall, I couldn't help but glance at Cabin Three, the Poseidon Cabin. The lights were dimmed which meant Percy was already at his table. I smiled at the thought. That guy could easily eat like a starving satyr.

But when we sat down at our table, I saw that table for Cabin Three was empty. Percy, being the only half-blood child of Poseidon, was usually alone on his table, except for the times when Tyson, his Cyclops half-brother, was visiting.

Chiron pounded his hoofs and everyone turned to him. "Welcome, campers," he said. "I would like to inform you that capture the flag was rescheduled and will happen on Tuesday, instead of Friday. Instead, we would have chariot race on weekend."

The campers cheered, with Cabin Five, the Ares Cabin being the loudest.

After burning offers to the gods, everyone started eating. I, however, kept glancing at the Poseidon table. Percy wasn't there. I felt bad. I should've just forgiven him when he said he was sorry, but I was so hurt seeing him being kissed by another girl.

I wondered where he was.

Dinner was over and he still hadn't showed up. Now I was getting really worried. We were heading to the ampitheater for the sing-along. I sat down with the rest of my cabin while my neck did some nearly impossible twists looking for him. I decided to talk to him but he wasn't anywhere.

Then Will Solace, from Apollo Cabin spoke up, "Hey, everyone. So, usually my cabin leads the sing along but tonight," he said, grinning from ear to ear, "we have a special performer."

I frowned in confusion. Special performer? What was he talking about?

Then I saw him, holding an acoustic guitar. His hair was on its usual messy style, his sea-green eyes uncertain and nervous. I heard some girls squealing behind me and I glared at them. Seaweed Brain holding a guitar? Something was terribly wrong.

"Hey," he said uncertainly. "So, um, I did something awful." He scratched the back of his head and I hear girls swooning around me. Ever since he defeated Kronos, Percy had become the most popular and desirable camper. They were constantly hitting on him. "And because of my stupidity, I hurt someone," he continued. "Annabeth," he announced, looking at my eyes and I felt my cheeks burning. "I'm so sorry. This song is for you."

Song? Di immortales, Seaweed Brains' going to sing? And about to play guitar?

He started strumming the chords with Will and two more Apollo campers backing him up. He then started singing.

When I look into your eyes
It's like watching the night sky
Or a beautiful sunrise
There's so much they hold
And just like them old stars
I see that you've come so far
To be right where you are
How old is your soul?

Oh, gods, I thought, his voice is beautiful. It was husky, and very sweet. How come he'd never sang for me before?

I won't give up on us
Even if the skies get rough
I'm giving you all my love
I'm still looking up

I felt my eyes tearing up. Listening to the lyrics and hearing his voice and knowing he was doing this for me really made me cry. Before I knew it, tears were falling down my cheeks. I wiped them away stubbornly; only to be replaced with new sets when Cayden, Klein and Calvin from the Demeter Cabin stepped towards me, holding bouquets of flowers. I nearly drowned when they handed me each one.

"From Percy," said Cayden.

I blushed deep red, of course.

Meanwhile, Seaweed Brain was still singing.

And when you're needing your space
To do some navigating
I'll be here patiently waiting
To see what you find

'Cause even the stars they burn
Some even fall to the earth
We've got a lot to learn
God knows we're worth it
No, I won't give up

Okay, that was a bit unsettling. What was he saying? I mean I know it was the song but why would he include those lines? There's no way I would let my relationship with him end. But still, hearing him say he won't give up on us was so sweet I started crying again.

I don't wanna be someone who walks away so easily
I'm here to stay and make the difference that I can make
Our differences they do a lot to teach us how to use
The tools and gifts we got, yeah, we got a lot at stake
And in the end, you're still my friend at least we did intend
For us to work we didn't break, we didn't burn
We had to learn how to bend without the world caving in
I had to learn what I've got, and what I'm not, and who I am

I won't give up on us
Even if the skies get rough
I'm giving you all my love
I'm still looking up, still looking up.

I won't give up on us (no I'm not giving up)
God knows I'm tough enough (I am tough, I am loved)
We've got a lot to learn (we're alive, we are loved)
God knows we're worth it (and we're worth it)

I won't give up on us
Even if the skies get rough
I'm giving you all my love
I'm still looking up

He played the last notes and looked at me, smiling that lopsided grin that I used to annoy me so much at the beginning. A lot of Aphrodite campers were looking at me in envy. They weren't the only one.

I stood up and walked towards the stage, putting my bouquets down.

When I reached him, he said, "I'm really sorry, Annabeth. Honest. I didn't mean to just stand there and let her kiss me." There was a collective gasp all around us. "I hope you can forgive my stupidity. Really, I'm sorry, just – "

I grabbed his face and pulled him down and kissed his lips. He smelled like the ocean, as usual and his lips were warm. His hand automatically fell to my waist, pulling me closer to him. My hands shot up and combed through his untidy hair.

I couldn't care less with our audience except Chiron pounded his hooves again and we were forced to pull apart. He was grinning stupidly at me and I slapped him. I didn't try to soften it.

Percy was obviously shocked. But I kissed him again. "Remember, I'm the only one with the authority to kiss these lips. They're mine," I said after we pulled apart.

He grinned. "Got it, Wise Girl."
