Friend forcing me to watch as he rearranges his bookshelf in Skyrim: Why do you hate literature so much? Is being a bookseller that traumatic?

"Sebastian, Y/N, so glad you made it!" Susan Downey smiled warmly at the couple. "Of course, we couldn't miss the 56th birthday of the one and only Iron Man," Sebastian chuckled, walking into the house with his girlfriend. He put his arm around Y/N, observing the place. "Guys! Hello!" they heard.

"Mr Downey," Y/N greeted politely, turning to smile at the birthday boy. "You must be the girlfriend," he grinned, pulling her into a bear hug. "Yep, that's me." Then he turned to Sebastian, frowning. "Why didn't you introduce her to everyone sooner?" Y/N laughed as Sebastian rubbed the back of his neck, shrugging.

"Don't ask me, she was the one too chicken to meet you!" Sebastian defended himself, narrowing his eyes at his girlfriend. She snorted as Robert let go of her, returning to Sebastian's side. "I guess that's on me," she sighed dramatically, making both men laugh. "Well, enjoy yourselves! Have a drink, have fun!"

With that, he walked away. Sebastian noticed a server holding up a tray of drinks and called him over. He handed a glass to Y/N and took one for himself, taking a sip. "Thanks for bringing me over, honey," Y/N smiled and he turned to her, scoffing. "You're my girlfriend! God knows they were dying to meet you," he laughed, giving her a kiss on the forehead.

With that they went around the place, talking to new people, old friends and making new acquaintances. Y/N had a lot of fun meeting Sebastian's co-stars, and especially loved Elizabeth Olsen. Y/N was a huge Marvel fan and one of her favorite works of the MCU was WandaVision. Y/N had fangirled a bit, not gonna lie.

Like that passed an hour. After her feet started hurting, Sebastian decided it was time for the woman to sit down, have a drink and chill out. "Okay doll, here's a glass of champagne, if you need anything at all, don't hesitate to call me, okay? I'm going there, with Chris and Anthony. I love you." She smiled when he gave her a quick kiss.

"I love you too, and don't worry, I'll find you easy. This place isn't that big."

"I heard that!"

Laughing at her antics, Sebastian gave his girlfriend one more loving kiss before prancing out of the room in search of his best friends, Chris Evans and Anthony Mackie. Y/N relaxed on the comfortable couch with a sigh, sipping on her drink. It all began a year ago, very cheesily, might I add.

Y/N was at her favourite coffee shop when he had walked in. Immediately, fans had him surrounded, but she didn't go over to him. She stayed seated, looking at him, wishing she could go over but she knew how stressful fan interactions were for celebrities. Sebastian had, unfortunately, caught her eye and she had turned beet red, burying her face in her laptop.

He had found her absolutely winsome and after the crowd around him had dissipated, he had wandered over to her table and introduced himself. She was flustered around him, which made him tingly inside. And he had blurted out, "Wanna meet here next Saturday at 7?" They kept their promise and that's how they started dating.

A year ago.

That was a healthy amount of time.

Right?

Y/N couldn't help but have her doubts. All her previous relationships were pathetic failures, where the guy usually got bored of her within 3 months. But now, she had braced herself for rejection (which she knew deep down wasn't coming but it pays to be careful). "Hey."

Startled, she turned to see a kinda young, kinda drunk woman sitting next to her, looking up at her with doe eyes. "Hi," Y/N smiled back politely. "You're— you're the woman!" She had started slurring her words, which made Y/N frown a bit. "I'm… what?" she blinked. "The girl! Who came over with Sebastian Stan, you're his girlfriend!" The woman laughed loudly.

A few heads turned towards them but quickly looked away when they realized that the girl was drunk. "Yep, that's me. Why?" Y/N was now amused. As they talked, she didn't notice Sebastian walking into the room. He had come back to ask Y/N something but had paused in his tracks when he saw her frowning at the young, drunk woman.

Then he inched closer, unabashedly eavesdropping on her conversation. "Yep, saw him spending a lot of time with Ms Lizzie Olsen. If he was mine, girl, I would take that man home and show him who truly belongs to him, if you know what I mean," the girl winked and a sad smile bloomed on Y/N's face. "They're good friends, of course they're gonna spend time together."

Sebastian smiled at her answer. He knew she was different, she didn't get easily jealous and he liked that, since it reduced the number of arguments they had by a lot. His jealousy? Well, that's a story for another time… "You don't mind? He seems to be spending a lot of time with her…" the drunk woman frowned at Y/N.

Well, she was drunk, she wouldn't remember this night anyway, so maybe… it would be good to get some things off her chest.

"No."

"Why not?"

"Because I braced myself for this months ago. They leave, they always do. It's nothing new," Y/N admitted, swirling the champagne that was swimming in her half-full glass. Sebastian's heart shattered into a million pieces at her words. Before the words were even completely out of her mouth, tears had started stinging in his eyes.

"Y/N?" Startled yet again, Y/N turned to see Sebastian smiling at her. "Seb! Hi, thought you were with your friends!" she grinned at him. "I— uh— something came up, we need to go," he spoke quietly, fidgeting with his hands. Y/N's brows furrowed but she got up, collecting her coat and her purse.

"Can we at least say Happy Birthday to Robert?"

"Yeah, yeah of course." Sebastian managed a weak smile when she gave him a kiss on the cheek, going off to find Robert and Susan. She told them something urgent came up and they allowed the couple to leave. "Seb, let's go!" He followed her out of the house, meekly trailing behind her, the words she said ringing in his ears.

They leave, they always do. It's nothing new.

How had this woman, practically a Goddess, had such bad experiences that she was forced to think that way? He was never going to leave her, having found the perfect woman at last. He got into the driver's seat of his car, and the car ride home was quiet. Y/N was getting anxious. What happened to him? Did something happen at the party?

Once they were home, Sebastian couldn't help himself. "S—" Y/N yelped when he crushed her to his body, hugging her tightly. He took both of them to their shared bedroom, sat down on the edge of the bed, pulled her on his lap and buried his face in her chest, breaking down. "Seb, honey, what's wrong?" Y/N cooed, getting insanely paranoid.

The crying didn't stop for 15 minutes. Y/N, in a futile attempt to get him to stop, was running a hand through his hair, whispering sweet nothings in his ear, holding him close. When he took in a shuddering breath, he pulled away and finally looked Y/N in her eyes. "Now are you going to tell me what happened?" she smiled gently.

He took her hand, pressing a kiss to her wrist. "I'm sorry," he croaked out and Y/N frowned. "Sorry for what?" He shook his head, burying his face back in his safe haven. Except, Y/N wasn't having any of that. She pulled him away and dropped a soft kiss to his forehead. "Tell me what happened."

He took in another shaky breath.

"I… I heard you."

"Heard me?" Y/N blinked. "Yes. You were… you were talking to that girl on the couch and she was— she was talking about how I seem to be spending a lot of time with Lizzie and you— you said you didn't mind but she kept on insisting and you said they leave. they always do. I'm not going to leave you, Y/N, I promise. You're one of the best things that has ever happened to me and I'm not letting you go."

Oh.

"Seb," Y/N whispered, her own eyes now filled to the brim with tears. "Don't cry," he chuckled with a watery voice, wiping her tears off. "It's just— all my relationships before you… the guys were assholes. They always left 2-3 months in. I— I wasn't taking any chances with you, you know… plus, you're kind of a famous guy and you can get so many better women—"

He didn't want to hear it. Better than Y/N? Impossible. He pressed his lips to her, immediately deepening the kiss when she reciprocated. "I promise you, I cannot do any better than you." Y/N smiled shyly at his words and his heart filled with happiness. "Let's go to sleep."

Both of them tired from the crying, they got undressed without trying any funny business. Y/N put on her usual pair of shorts and one of Sebastian's huge t-shirts, getting into the bed where a boxer-clad Sebastian already lay. He pulled her into his arms and she rested her head on his chest, draping an arm around his taut abdomen.

"Comfy?"

"Yeah, you?"

"Yeah. Goodnight, doll, I love you."

"I love you too, Seb. Goodnight."

"...Never gonna leave you."

"Not a chance."
