永遠記憶 – Eternal Memories
Chapter 1: 心: Heart

"Eren, please promise me that you'll come back."

"Captain… You know I can't promise you anything…"

"If you ever lose control of yourself, don't think I won't find you and kill you."

"Haha, I'm well aware of your task, Captain."

"…."

"…Captain?"

"…what do you want now, shitty brat?"

"Can you promise me something?"

"…? If it's plausible, I'll consider it. What is it?"

"Promise me that you'll be happy and find someone when I die."

"Tch, you little shit. I won't promise such a thing, and you won't die. Have faith in yourself."

"Heh. You're right… it was just a stupid thought…"

"Oi, Eren, are you crying? I'm sorry—"

"I'm not crying!"

"Yes, you are. I'm sorry Eren; I can't promise that because I will find you for as long as I live. I will keep bringing you back, here with me. You and I will always be together."

"Captain…!"

"Now stop crying, your uniform is all drenched and filthy."

…Why are my dreams always of him? It's like we lived another life where we knew each other…

My dreams… always consisted of recurring deaths of me as a monster. And he cried for the first time, he held me close, and shook me as though as I was just asleep.

"Eren, please… Don't give up on humanity; don't give up on me! Open your eyes…"

Good morning, please wake up!
Good morning, please wake up!

GOOD MORNING, PLEASE WAKE U-

Click.

I groaned sheepishly and turned, burying myself on the pillow. I could hear the rain pouring down outside and the coldness brushed through my skin and I shivered, grabbing the blanket. After I wrapped myself around the warm of the blanket, a small body wrapped its arms around me, and I smiled slightly to myself.

"Daddy…" my little girl mumbled as she snuggled closer to me in her sleep, "we're going to be late for school…"

My little girl—Petra—she's five years old.

See, I found her at the front of my doorstep five years ago. Back when I was still in junior high, I moved out of my parents' house because Mikasa got married and had two children. They said that I was responsible enough and I live on my own—with their support with financial stability of course. But going back to Petra…

Mikasa and I have no information about Petra's real parents and their whereabouts.

But I feel like I have known Petra my whole life. I refused to give her adoption agency when my parents and Mikasa suggested doing so. In the end, we ran over the adoption process and took her in as my own.

When I held that child in my arms, she opened her hazelnut eyes and reached out for me.

Petra never cried, even though it seemed unhealthy for a baby not to cry, I raised her all on my own and I have never, put her on the verge of tears. And I don't intend to.

I played with Petra's hair as I sighed in content. My daughter was wide-awake and she sat up at the edge of the bad to tie her ginger colored hair. "Daddy! I'll make us some hot chocolate!"

"Thank you, Raru," I chirped, kissing her forehead before she dashed down towards the kitchen.

I too, sat up afterwards and reached for my red jacket to wear over my boxers. I stood up, looking out of the windowpane and watched the stream of rain running down against the glass. My phone rang a few minutes later; it was my sister, Mikasa.

"Hello?"

Good morning.
Eren, have you watched the news yet? There's a storm heading towards your town.

"Actually, I just woke up with Petra. I guess I'll call off work and stay home with her."

Yes, stay safe. I'll call you tomorrow morning.

"Thanks Miks, talk to you tomorrow."

When I reached the kitchen, I sat down at the dining table and patiently waited for my daughter who was standing on the stool to make hot chocolate for the both of us. "Raru, your auntie called and said there's a storm coming so you won't be able to attend school today. It's too dangerous for you to go out there, is that alright with you?"

My baby girl didn't whine or complain about my decision. "Hold on daddy—" she stepped off the stool and grabbed the two hot chocolates and placed one in front of me. "It's okay if I don't go to school! If it's with you, I always have fun dad!"

"Heeeh? Where'd you learn to kiss up like that huh? —" I started ruffling her hair.

Petra giggled and reached for my hand, "Daddy, stop that! I got it from you!"

I laughed and picked her up with my left arm, my other hand was occupied with the hot chocolate she made. "Daddy feels like playing games, is that okay?"

She pouted, "Can we have a short Pokémon marathon for a bit before you play? I didn't get to watch last night because we went to auntie's house and I played with Asa and Mimi all night!"

I smiled and obliged to her wish as I placed her on the couch with our hot chocolates on the living room table. Petra watched with a smile plastered on her face while I plugged the television to an outlet and turned it on to Pokémon.

"Here," I handed the remote to her, "don't put the volume up too high. Daddy's going to work on his essay instead."

"But dad, I wanted to watch with you…"

"Alright, fine, Raru. Let me just get my laptop, alright? Pause your movie for a bit."

It was so cold even though the AC wasn't on. The rain was still pouring hard outside when I got to my room; I reached for my laptop, grabbed a blanket, and Petra's jacket so that she would be more comfortable on the couch. I started debating whether I should heat up some popcorn and watch a few episodes with her before I start on my essay until the bell rang—

"Raru, check who it is please!"

I could hear Petra running towards the door. "Who might you be?"

A pause. "Dad! Vivi is here!"

My heart skipped a beat. I grabbed all of the things I had and took it with me to the kitchen then down the hall to open the door for my next-door neighbor.

That's right, Levi Ackerman is my neighbor.

We've known each other since we were young. I was still in elementary when he was in junior high, but my parents relied on him a lot because he was very mature for someone his age. He's pretty short, but he's actually reaching his 30s in about two years.

"Levi-san, hi. Come in!"

"Vivi, did you come here to watch Pokémon with me and daddy?"

Levi's silence gave it away and I slightly smiled when he picked Petra up into his arms and poked her nose. "Yes, it's a good weather outside. It sounds like a good plan to watch with you and your dad."

I headed to the kitchen and Petra was wailing happily when she was placed down then back to the couch. Levi followed me with a bag of groceries in his hand.

"I thought it was better to have a reason to come here."

I chuckled, "thanks Levi-san—"

"I told you to just call me Levi, you shitty brat. We've known each other for so long already."

"I know…" I pouted and scratched my head in embarrassment. "It's just a habit now, I guess…" I turned to the sink. "Where did Erwin go?"

"Tch, that bastard went off with another girl again. I really don't give a shit anymore."

I sighed and unpacked the goodies and fruits from the grocery bag, "that's not a good thing to say about your boyfriend. You need to talk to him about it." I placed a popcorn inside the microwave.

Beep.

"There's no point talking to him about it if he keeps doing the same thing over and over again. It's a drag—I will slit his throat the next time I catch him with another woman."

I laughed nervously, "well if you were only with Petra and me…"

His eyes darkened, "Hah? What are you talking about?"

"Oh, nothing," I said while placing the fruits in the fridge. "Just talking to myself…"

Levi walked towards the living room where Petra was watching Pokémon, holding her hot chocolate with two hands and a blanket over herself. She was so comfortable, I smiled at the sight of her and Levi talking and watching the movies together.

Beep. Beep.

After I grabbed the popcorn out of the microwave, I poured it on a bowl then sat on the other end of the couch, while Levi sat on the other with Petra in between. We watched Pokémon in silence; the sound of the television ringing to our ears and the sound of rain pouring on the roof of our apartment complex was all that was heard.

I turned and studied Levi who was so indulged at the movie but he felt my eyes so he turned and glared at me. "Spill, brat. What's bothering you?"

Petra looked up after pausing her movie. "Are you okay daddy?"

"I'm fine!" I said waving my hands, "I'm just incredible cold!"

Petra reached for Levi's arm and mines; she wraps Levi's arm around my shoulders and she giggles at our warmth. Levi didn't seem to mind the closeness between the three of us although he had a mortified expression on his face.

Ah. Shit.

Did I forget to mention?

I'm madly in love with Levi Ackerman.

Too bad he's already with another man.
