TONY
Ah, what would I say? A christmas with the richest man on earth couldn't be more festive. He knows your favorite holiday is christmas, he's trying his best to make you happy. Sometimes it's cute when you found him working on something for your christmas presents and he'd be like, "Y/N! How many times do I have to tell you to sleep and DON'T even go to my lab, sweetcheeks?".
Last year he gave you a private jet, and took you to Australia to had a dinner and flew back to Paris to do some adult stuff. Sometimes you wonder, would this year he give me Saturn?
STEVE
There's nothing better than watching your dad talking excitedly with your boyfriend while you and your mom giggled. Yes, a christmas with him is always homey. He'd just visit you and bring some red wines. Steve and your big family would have a dinner when they wouldn't stop bombarding him with questions. "Your family is the best family, Y/N"
Last year he gave you a nice lilac dress and an earrings. You wore this dress for the anniversary.
CLINT
Travelling. From forrest, to mountains, to beaches. Anything, really. Just mention it to Clint and he would take you there right away. A christmas with him is always adventurous. You both have travelled around the world. And that's you love the most, it feels like the world belongs just for you two. "All these breath-taking views, you're the only one who can make me breathless."
Last year you both went to Bora and spent a week there. You took a lot of selfies together.
THOR
Anything about this world is strange for Thor, especially christmas. He had no idea what that is until you told him everything. And now, he's kind of a christmas-freak. A christmas with him is always exciting. Because both of you would spend a lot of time playing snow, or teach him how to skate, and chatting near the fireplace while drinking hot chocolate. "You know, Asgard is absolutely nothing compared to this cozy couch and warm fireplace."
Last year he gave you sweater that he claimed he made it by himself. Even though you didn't believe him, well, you see no brands on it.
PIETRO
Kids, a lot of kids. You have a lot of cousins and siblings. That's why you love (or hate) about christmas. All the kids love the idea that you are dating a bad-ass hero so every christmas you invited him over to dinner, and pleased the kids of course. He'd come after dinner and the kids would sprinnted and hug him. Your parents, uncles, and aunts love him so much that everyone thinks he'd make a good husband and father. A christmas with him would be sweet. "If you wanted to run as fast as me, Jack, you have to practice every single day and drink a lot of milk!"
Last year he gave you a giant teddy bear, twice your height. It's so hugable. And not to mention he sprayed his perfume all over it and so it smells like him.
BRUCE
He's always so busy. That's why he always try his best to work before christmas and take a holiday on christmas so he could spend christmas with you. He's not really a fan of christmas so you both decided to celebrate it with fancy dinner or other simple activities. A christmas with him is always relaxing. "I think tomorrow i'd take a day off. Yeah, this day with you wasn't enough."
Last year he took you to London, you both spent 3 days in England.
LOKI
Just like his brother, he's also a christmas-freak. He loves to sing all the christmas's song, watch every christmas's movie but he wont admit it. He insisted the reason he loves christmas because green's everywhere. A christmas with him is always surprising since what he's good at is magic. "Look at this empty box, and now with the power of my love for you.... tadaaaa! Do you like the dress?"
Last year he gave you too many presents and surprises. Start from the early morning, he gave you a bucket of roses until the night he gave a golden shiny necklace.
BUCKY
Yes, he's used to be a flirt. But his romantic attitude doesn't fade. He loves the idea that you're always so excited about christmas. He's fine with christmas, but seeing you happier than ever, is what he loves the most. A christmas with him would be cute since he knows how to treat his girl right. "I love christmas, because christmas makes you happy."
Last year you both went to Disneyland and he took a lot of aesthetic candid picture of you and you begged for him to send them to your phone. But better, he made a scrapbook full of your candid and gave it to you as 'a week after christmast' present.
