April 28th, 2012.

Summer never believed this day would have come. Well, yeah, sure back in college she pictured it many, many times but after everything that had happened between her and Seth in the middle of their senior year, she felt like it was just some fantasy she kept wishing to come true. Now it was truly happening. She was honestly standing in her white gown in the middle of the older Cohen's guest bedroom in Berkeley, peering at herself through the floor-length mirror.

She had given Seth the photo album of candids that she – and others – had collected over the past eight years three nights before. Seth was shocked and he started choking up as he tried to thank her. He couldn't seem to form any sentences for his appreciation – something that had shocked Summer – and instead showed his thanks physically. The night had been amazing; more amazing than she could ever remember feeling with Seth. He was so gentle, so attentive, so passionate that Summer felt more loved by him than by anyone else she had ever known combined.

Summer hadn't seen him since that night. Which, after their break-up two years ago, was the longest time she had gone without seeing him. They had both agreed well into the planning of the wedding that it would be so much more special if she was walking down the aisle and he was standing at the alter if they hadn't seen, touched, or spoken to each other in seventy-two hours.

Summer had started to go stir crazy only hours after she and Seth had parted after their last – single and unattached (technically) – night together, trying to call him. Taylor had snatched her phone away and then declared herself Summer's guard dog, making sure she didn't slip up again until the wedding.

Summer had never regretted anything more than agreeing to that seventy-two hour separation.

'Okay,' Summer rationalized in her head, 'Maybe there's a few other things that you regret more,' thinking back to their whole fiasco that was senior year.

But she wasn't going to go into that, she decided as she shook her head of her thoughts. Because this was her day. Her and Seth's day. And eight years was way too long to wait for something as monumental and exciting and thrilling as this. As becoming Seth Cohen's wife. Mrs. Cohen. Mrs. Seth Cohen. Summer Elizabeth Cohen.

Oh God, she felt like a five year old in a candy shop.

But she couldn't help it. She was just so damn happy.

And it certainly didn't help that her hormones were running amuck. Her pregnancy hormones. Another reason she had been dying to talk to Seth for the past seventy-two hours.

She had been suspecting it since the end of March. But she had been so engrossed in the last minute details of the wedding that she just chalked up all the symptoms to stress. But by the middle of April, Summer started thinking the 'what if's.

"What if it isn't just stress? What if it's something more? What if I'm pregnant?"

She had been on the pill. But Seth never used condoms. And the pill was sometimes proven ineffective. This fact was proven by Taylor, whom had gotten pregnant at the beginning of her sophomore year at the Sorbonne even though she was on the pill.

So Summer ended up buying three pregnancy tests – planning on one being ineffective and two still not feeling effective enough – and took them all during a night when Seth was out with Ryan dealing with last minute honeymoon trip details.

All three came out positive. And Summer cried. But not because she was scared or upset.

But because she was happy.

Summer was in the doctor's office for an appointment to confirm the pregnancy two days later.

And that solidified it.

Summer Roberts was pregnant with Seth Cohen's baby. And she was seven weeks along. One month and three weeks exactly. And the baby was due December 1st. Making it a Chrismukkah baby. Just about two years younger than Ryan and Lana's daughter, Tessa.

And Summer couldn't have been more thrilled.

Summer immediately had decided not to tell Seth until after the wedding was over and they were on their honeymoon in Tahiti. (Seth's only choice that Summer hadn't fussed with concerning the wedding.) She decided it would have been less stressful that way – without Seth worrying about her or worrying (as he inevitably would) that she would react the same way she had last time. So she kept it hidden from him – and from virtually everybody else – but itched to tell him every second of everyday. And these urges only increased ten fold when he had made love to her three days prior and she literally had to bite her tongue from letting the joyous news slip.

She knew Seth would be just as excited as she was. She didn't have a second thought in her mind. This was it. And it was right.

Summer searched for her bag that she had brought with her to the Cohen's Berkeley home earlier that day to get ready, knowing she wanted to take a few moments to herself to read a couple pages from her high school diary.

She flipped through the yellow colored pages (the coloring as a result of years passing by) searching for the entries she wanted to read most. Summer had remembered specifically writing about wanting to marry Seth and have children with Seth and grow old with Seth and now, as she stood in her nearly $10,000 wedding gown (Cause who was she kidding? She was a Newpsie at heart but, unlike other Newpsies, she only planned on marrying once) she wanted to relive those unspoken dreams of her seventeen year old self.

As Summer skimmed the pages, she found the entry she had most wanted to read. It was dated February 15th, 2006. More than six years ago. Summer's eyes followed the words that came after the date…

So I had sex on the beach last night. Yup. Me. And not like that alcoholic drink or anything. The real deal. With Seth. (God, my dad would KILL Seth if he ever saw this!!!) I wasn't planning on it. In fact, I was planning on staying pretty pissed at Seth after all of his stupid Coheny Cohenisms he's been up to lately. All the lying – not going to his Brown interview and smoking pot were the biggest. (And if Sandy or Kirsten ever saw this, now THEY would kill Seth. Ha.) But he was just so adorable when he asked my father if he could speak to me, even though I was standing right there. It was too cute. And then his present… oh, God! It wasn't like anything expensive. Well, unless you count the underwear he gave me earlier in the day (which turned out to be a present for his mother instead… EW! Not from Seth of course. From Sandy. Double EW!!). He wrote on a napkin all the things he had lied about recently and gave it to me saying that I should give it to his parents should he lie to me ever again. And I know – because I know Seth – he will lie again. He'll probably lie until he's blue in the face some other time in the future because it's part of who he is. But he was just so sincere about it last night… it was like he actually believed that he would never lie to me again. That he would forever tell me what he was doing and whom he was doing it with every second of every day. His face looked so innocent I just couldn't help myself. And so happened the sex on the beach. And everyone has their own opinion of it (well, anyone who has ever done the deed on the beach) and I didn't think it was all that bad. I asked Taylor earlier today if she had ever done it on the beach. And surprise, surprise, of COURSE she has. But she said the first two times (!!) it was pretty bad. She said we were lucky we got it right on the first shot. Yeah… that conversation ended there. I would have asked Marissa if she had – besides her time in the Tiki Hut with Ryan at the beginning of the year – if she hadn't been so MIA lately…

Anyway, it was awesome. But I don't think it will be happening again anytime soon. It was more like a one time thing. Plus, I think Seth got a rug burn from the blanket so I don't think he's looking for round two anytime soon. He seemed perfectly content with my bed this afternoon as it was…

I know this whole entry sounds like I'm some over-sexed, hormone racing teenager but I'm not. Honestly. I love Seth. More than he knows. More than anyone knows. I know I should voice it to him more often but it's hard. I wasn't brought up that way, you know? But regardless, he's the most important person in my life. Way past either of my parents or Marissa. He's the only one who's there for me anytime I need him there. Or even the times I don't know I need him there. He's just it. And yeah, he's been on a pretty fantastic lying streak lately and yeah he's still into those dorky comic books and video games, but it's who he is. And I read in this book once – well, it was more of a self-help book I became strangely obsessed with the summer I turned sixteen while Seth was away – that you know you're really in love with someone when you find their faults more endearing than annoying. And that's EXACTLY how I feel about Seth. He's amazing.

Summer felt some tears slipping down her cheek but she didn't move her hand to brush them away. Instead she kept on reading over the words her teenage self wrote so long ago.

I want to marry him. Which I know is crazy ridiculous for a seventeen year old girl to be saying nowadays, but I do. And I daydream about it a lot. Marissa will be my maid of honor and Ryan will be Seth's best man. They'll probably already be married because they would have had enough of all the break-ups and make-ups they had in high school and got married in some chapel in Vegas. But Seth and I will have a big church wedding. With everyone we've ever known in attendance. Including Anna – just to show her that I wasn't just some childhood crush to Seth. And Sandy and Kirsten will be proudly looking on as my dad – and my mom (cause she'll come back to get to know me and tearfully regret losing time with me during my teenage years) – look proudly on as well. Then after the reception and after all the alcohol has run dry, we'll jet set on one of Seth's grandfather's private planes to somewhere completely exotic. Where we'll just enjoy being together and talk about our future and make love anywhere and anytime we'll please.

(Maybe the second happening of the beach sex will occur then. Wink, wink.)

And then I can picture us having children together. Not a lot because I heard that ruins the sex life in a marriage and I certainly won't let THAT happen. But a few. Maybe two. A boy and a girl. But the boy definitely first because I want to see Seth with a little mini-me. Can you imagine?? A tiny dark curly haired toddler sporting polo shirts, chino pants, and Chuck Taylors on his feet. Oh my God it would be ADORABLE!!! I want that so bad. Not right now. But in the future. After we both graduate from Brown and get married and move back to California. (Because after four years on the East coast surely Seth will want to come back to warm weather all year round – no matter how much he hates Orange County. Besides, if I follow him to college, it's his turn to follow me after we graduate. And me? On the East coast for the rest of my life? Uh huh. I don't think so! I'm already dreading the snow and cold temperatures as it is…)

This is what will happen. I'm sure of it. I guess it probably won't happen exactly like that because obviously things change but me and Seth staying in love, getting married, and having children? Nope. That won't change. I won't let it.

This is probably cheesiest thing I have ever written in my life. And if Seth saw it… oh, I can't think about that. He'd tease me about it to no end and never let me live it down. And then he'd have the upper hand in our relationship. And I have kind of grown accustomed to him worshipping the ground I walk on so I will guard this thing much more now that I've written this.

Ow. My hand is really starting to cramp up. I don't know if I've ever written this much… It's 6:30!! I was supposed to be at Seth's house fifteen minutes ago!!! Wonder why he hasn't called… oh crap! He called five times. Damn school forcing me to put my phone on vibrate and making me forget to turn it back onto regular volume when I leave.

I gotta go. But everything I wrote in here in the past hour? Yeah… let's keep it between us.

XOXO,

Summer

"Hey, Sum…?" a voice called out to her, causing her to drift her eyes away from the now tear-stained page in her long lost diary.

"Yeah?" Summer croaked back.

"Oh, Summer," Kirsten rushed to her side, letting her arms fall around the beautiful petite girl's body. "Everything's going to be fine."

Summer shook her head, smiling as she did so, causing a questionable glance from the older woman. "No, I'm not scared. I'm just happy. So happy." Summer paused for a moment as she watched her soon-to-be mother-in-law's facial features turn into a smile. "I love your son more than anything else in the world. I want you to know that."

A few tears slipped down Kirsten's cheeks, nodding her head in reply. "You didn't have to tell me. Words are pretty meaningless when I see the two of you together."

Summer dropped the book to her side and leaned into Kirsten, letting her arms snake around her body for a tight hug. Kirsten returned the favor, squeezing her gently. The older woman pulled back, staring into Summer's eyes, whispering, "Now we have to stop all of this cheesiness before your make-up is ruined."

Summer laughed, leaning towards the mirror to touch herself up. "You sound just like Seth."

Kirsten shrugged, heading towards the door, "It's the Cohen way. Better get used to it."

"I can't wait," Summer replied honestly, turning towards Kirsten and making her way out the door towards the foyer where Taylor's four-year old daughter, Genevieve, stood in all her blonde ringlets and tiny white dress, holding a basket of flowers, and Lana and Taylor stood beautifully in their maroon bridesmaid dresses. Kirsten lined up with them, as all four of the most important women in Summer's life – or girl in Genevieve's case – looked on at her with loving smiles.

Genevieve tugged at Summer's dress lightly, making Summer's eyes cast down a few feet. "Can I go out now?"

"As soon as the music starts playing, Gen," Summer leaned down.

And as soon as the words left Summer's mouth, the music began to play and Genevieve giddily moved back into place, smiling happily over to Summer. "So I can go now?"

Summer looked over to Kirsten, Taylor, and Lana who were lined up in that order behind Genevieve, ready with their own bouquets in hand. Kirsten handed Summer her bouquet of white lilies – still her all-time favorite – with tears rimming her eyes. Summer looked back down to Genevieve, "Whenever you want to start walking, you can."

Genevieve immediately turned her back to the other four women and went through the door, into the sunlight.

Kirsten moved closer to Summer, giving her a tight squeeze on her arm. "I know we still have a whole ceremony to go through but…," Kirsten trailed, "Welcome to the family, sweetie."

Summer nodded and said her thanks as Kirsten then made her way out the same way Genevieve left.

Taylor then took her turn to approach, leaning in and whispering, "You're telling him tonight, right?"

Summer had let it slip to only Taylor and Lana while on her bachelorette party that she was indeed pregnant and wanted to keep it quiet until the wedding was over so they both needed to help her avoid any alcohol that would inevitably come her way. She also didn't want anyone to become suspicious so she also insisted that they help cover for her. Because if that many people knew, it would definitely get back to Seth. And Seth probably wouldn't be happy that he was one of the last people to know that he was going to become a father in a few months. So telling Taylor and Lana was certainly required.

Summer laughed, pushing Taylor towards the door. "Oh, just go already!"

Taylor obliged the bride's wishes and also left out into the sunlight, but not without leaving Summer with a wink and smirk as she disappeared.

It was then only Lana and Summer left in the Cohen's Berkeley house. Her best friend for nearly the past five years. No longer her substitute Marissa but now the best girl friend she had ever had. Her maid-of-honor. Summer's eyes grew wet as Lana approached her, grasping onto her arms as Lana did the same to Summer's.

"You're seriously getting married to Seth," Lana broke the silence.

Summer laughed, moving a hand away from Lana's arm to move up to her eyes in order to shoo away the tears that were threatening to fall. "Yeah, I guess I am."

Both women smiled at each other for a few more moments before Lana whispered – even though she didn't have to seeing as there was no one else left in the small hallway beside themselves, "I'm so happy for you."

Summer nodded at Lana's sincere statement, clasping back onto her best friend's arms.

Lana continued, "And I know your dad would want to be here with you right now. He would have been so proud of you." Lana paused for a moment, then adding, "So would have Marissa."

Lana never knew Marissa. And even though in the beginning of Lana and Ryan's courtship she grew envious of the deceased girl, she always remained mature about it. Opting to let her closest friends reminisce of the times when she wasn't there and when Marissa was, without complaining or saying a word. Lana knew Marissa was missed on this important day and she knew that even though she was now Summer's best friend, a small piece of Summer's heart wished her childhood friend could be standing there with her. There was nothing envious about that; Lana understood. It was just a simple fact.

"Oh my God," Summer hugged Lana tightly. "Are you trying to make me cry?"

Lana laughed into her best friend's shoulders, peeling back. "I should probably get going. People will start to wonder if I'm trying to convince you that you haven't made a mistake by choosing to marry Seth."

Summer laughed, nodding her head, "Yeah, people might think that. But Seth won't."

"Right," Lana agreed, "He'll think you're just crying about how happy you're gonna be with him or something."

"Which I am."

"Yes you are."

"I need to stop."

"Yes you do."

Summer smiled, "He knows everything."

Lana's eyes rolled. "Well, not everything. Just everything about you."

"Yeah… Which is why I'm marrying him."

"Ah ha!" Lana laughed as she approached the exit. "So now the truth comes out!"

Summer shooed her best friend away, "Go! I want to get married some time today!"

"You waited eight years. What's a few more minutes?" Lana cheekily replied, making her way out the door. "See you later, Roberts."

"That's the last time you get to call me that," Summer told her.

"I know. Which is why I said it," Lana leaned back into the doorway. "See you out there."

Summer smiled, watching Lana leave and it took a few more moments for Summer to sum up the courage to walk towards the door. She looked out – it was a beautiful, sunny, and warm day in Berkeley. There were no clouds in sight and there was no wind to mess up her hair. It was like there were people up there – past the skies and into the Heavens – that wanted this day to be perfect for her. And Summer knew who those people were – just as Lana had spoken their names a few minutes earlier.

Summer glanced over into the hallway mirror, checking her appearance one last time before peering down to her stomach. "Ready to go see daddy?" Summer cooed to her belly. She laughed at her antics, gathering the bouquet in both of her hands steadily as she walked out into the beautiful backyard of the Cohens' Berkeley home.

And as soon as she saw Seth's shoulders rise and fall – probably the cause of a breath he was holding in in anticipation – and his beaming face, she knew everything was going to be all right with them. And their baby.

And Summer just couldn't wait to share everything – her thoughts, her big news, their future, their life – with him.

For real this time.
