(Basically, it's one of you saying you like each other and the initial asking out... Yeah.)

Steve: About a week after he saw you shirtless, Steve had to go on an important mission. You were extremely nervous. He'd gone on missions before, but never one with such a low chance of getting out alive. "Be safe. Okay? If something happens to you... I don't know what I'll do."
"You'll be short a best friend."
"Steve! Don't say that! Gosh, I'd die if I lost you," you muttered. "I'll be fine. And if I'm not... Well, I'll be fine, we'll just stick with that." He smiled ear to ear. He gave you a huge hug, nearly crushing you. He ruffled your Y/H/C hair and opened the door. "Oh, wait!" you ran to your room and got an 80s smiley face pin that you'd had your whole life. "Here. Keep it, to remember me." You pinned it to his collar. "Like I could forget you." He smiled, and then he was gone.

You were not in good condition. It had been a week past the amount of time estimated for Steve to get back to you guys. No one could really sympathize with you, for no one cared for him as deeply as you. You were sitting on your worn down couch, simply staring at the blank TV. Your phone started ringing and you looked at it, scared and relieved when you saw it was Agent Hill. "We found him. Some agents are coming to pick you up now," she simply stated, and hung up, leaving you full of worry. When you got in the car, they apologized, and blindfolded you. Soon, you made it to what you assumed was SHIELD's headquarters. You were greeted by Maria. "Where is he?! Where is he?" you nearly yelled. "He's stable now, but, don't be crazy loud, okay?" she said, leading you into the building. You went into a room that had a bed, and saw it contained the Super Soldier, who looked pretty bad, for being a guy who didn't really get that hurt. "Y/N." He cracked a smile big enough for you and him combined. You began shaking and went to him, holding him like you'd never let go. "I'm okay. It's alright, I'm okay," he whispered. You held on tighter, because you weren't sure if he was actually there. "Hey, if I wasn't a super soldier, I wouldn't be able to breathe. Oh, hey, look." He opened the pocket on his suit, and pulled out the smiley face pin, all busted up and dirty. You couldn't help it, you started crying. "You're okay. You're really okay. I don't think I could've gone on without you. I... I need you. A lot, Steve."
"And I you. When I get outta this mess, I heard the guys who did this," he pointed to his arm cast," talking about some really good food."
"Uh, yes to the food with you, but I'm gonna go with not there, because we don't need a double-cast-Cap," you smiled.

Tony: You woke up with a piece of paper covering your face, (We'll keep it a secret that it made you scream.) saying, Don't flip out, but I broke your lock last night and wound up sleeping in your guest bedroom. As I write this, I am suffering a very painful hangover, and have decided to leave you be. ~Tony. You rolled your eyes and made your way to the door. As you thought, he was sitting outside it. "Come in, Tony," you smiled and dragged him through the doorway. "Noooo... I can't burden you."
"It's not a burden, hon. It's a pleasure. And camera-worthy moment," you teased. He poked you. "Shaddup. Do you have Toaster Strudel?" You shook your head. "Meh. You know what I really want?"
"What?" you asked, intrigued. "To talk to you over food thingys in the night without being drunk." You laughed at his terrible grammar. "A date?" "Yes, a date. That would be awesome, cause you're pretty awesome."
"You aren't hungover, Ton. You're still drunk. Find the bathroom, and if you feel better after that, we'll talk about that date." You smiled as he trudged off to the bathroom. Billionaire, genius, playboy, philanthropist, Tony. Tony Stark, whom your relationship with was coincidental, wanted to go on a date with you. How could you turn that face down?

Bruce: "Tony, you're really getting on my nerves right now." Bruce contained his snarl, in fear of getting too angry. "Bro, I've seen the way you look at her. You. Are. In. Love."
"She's too good for me."
"Bruce, listen to me, she looks at you-"
"Like I'm trash?"
"-that way too," Tony finished, bringing a small blush to Bruce's face. You drowsily walked into the lab. "Hi," you yawned- it had been a long night, with too much driving around, too many people, and lots of shots. "Hi, Y/N." Bruce smiled. "I'll leave you two. To talk about the things you love." Tony smirked and you heard whoosh as he walked out the automatic doors. "Gosh, he's annoying," you groaned and sat down at your desk. "Oh, I took part of the project home and was able to finish most of it, if you want me to take some of your section...?" Bruce asked. He was always doing stuff like that. "Nah, I'm good, but thanks." You smiled. He came over, looking at what you'd done. He was directly leaning over you and you had to resist not playing with his dark curls. "You could've used x's inverse instead of figuring out y. See?" he grabbed your pencil from behind your ear and did the equation again, much faster than you had. "Oh my gosh! Bruce, that's it! The inverse gives you the same property, but with a different time. We- WE'RE GONNA BREAK GRAVITY!" you squealed. "Wait, what?! We're actually gonna do it?! I'm a genius!"
"Yes, you are! You're amazing, Bruce!" you jumped up and hugged him. He stood shocked for a second before returning it. "I couldn't have done it without my faithful assistant."
"Modest. It was all you and Tony." You ruffled his hair. "No, seriously, I couldn't have done it without you. Thank you. I... I... I like you. A lot," he awkwardly blurted out.
"Shh... I'm enjoying my victory, an- Wait, what?"
"I like you, a lot, Y/N. I don't really know how to put it eloquently like Tony, or cute like Steve would, but I do. So... Yeah."
"Bruce, that was the perfect way to say it. I've liked you for awhile, too. Ever since I saw you in the restaurant." You smiled.
"Lunch?" you both asked at the same time. "Sure," he laughed and grabbed your hand and you ran off to the cafeteria, past Tony.
"I KNEW IT!" Tony yelled.

Clint: "I'm kinda busy. And worn out. Saved the world yesterday," Clint explained. "I didn't know that you..."
"It's 'cause I do my dang job, okay?" he snapped. You backed away, about to leave, when he grabbed the crook of your arm. "Listen, I'm sorry. It's just... Emotionally worn out, physically worn out, just kind of done," he apologized. "Yeah, I get it. I have those days."
"No, you don't get it... I just- I need to- I- Oh, to heck with it." he cupped your face and slammed his lips to yours.
"What the...? What?! Emotionally worn out, you say?" you said when you pulled away. (Not that you didn't enjoy it.)
"I was like that because I didn't know what to do, and my gosh, I'm on a high now. You wanna have dinner sometime? It'd be a pleasure."
"Barton! You just randomly kissed me! Are we gonna talk about that? Clint. Hello? You in there?" you sighed. "Yes. How does tomorrow sound?"
"Great! I'll be at your desk when you get off work," he said, walking out of the training room.
"When I get off work? Have you been watching me?!" you yelled after him. The ex-assassin smirked over his shoulder and shrugged.

Thor: "Thor. Listen to me, Ollie says he wants to see you."
"Dogs don't speak, Y/N."
"He does! He's like, 'ugh, where's Thor? He's cooler than you!'"
"No. Don't say that. You are better than me in every aspect, milady, even with your disability. Anyone would be lucky to know you." You blushed as he said this, even though he couldn't see it. You were about to bid each other your farewells, when he suddenly asked, "Would you like to have dinner sometime?"
"Oh, yeah, movie night's coming up. What should we-"
"As more than friends, Lady Y/N. If that would be okay with you."
"Thor, of course! We'll plan something, for a soon date."
"Goodbye for now, my fair maiden," he said and hung up.

Loki: "LOKI!!! How the heck did you get open a glued together shampoo bottle?! MY HAIR IS BLUE, LOKI!!!" you yelled through the phone. "Y/N, it'll come out, just don't use that shampoo again," he snickered. "If I could slap you right now, your puny butt would be three weeks past a year in the future," you snarled. "I'll come with new shampoo if you'd like," he offered. "No. I can get it."
"Oh, it was just a prank, love. You don't trust me?" You thought about it.
"If you put anything in it, the Asgardian God of Mischief will die."
"I believe you. I'm on my way now, doll." He hung up. Doll? Love? He'd never used those pet names before.

"Thank you." You smiled at the door, checking to make sure it hadn't been tampered. "Of course. Although, blue suits you better than Y/H/C."
"Why don't I believe you?" you asked, beginning the process of washing your hair again, just in the sink. "I don't know... I'm completely trustworthy, and we both like each other enough, no?"
"Oh, yes we like each other very much." You smiled. Ah, your hair was back to normal. "Actually, Y/H/C looks marvelous on you..." he whispered, and ran a hand through it, sending shivers down your spine. "Scratch that, darling. You're marvelous." You blushed.
"Loki, I can't help being myself. It's nothing spectacular."
"You're a beautiful mortal, did anyone ever tell you that?"
"Before you, no. But I'll gladly take it. Do you want to have dinner tonight?" you asked him, and he whispered a yes before sliding out your door gracefully.

Bucky: "Oh my gosh, Bucky. What happened last night?" you asked from the couch. "Well, you got pretty drunk. You tried to marry a chicken, and for about an hour you hid in the Men's Room, laughing devilishly when they ran off. Oh, and you made out with me. Or tried to."
"Oh, I'm so sorry." you groaned. This was one of the worst hangovers you'd ever had. (Still is to this day) He muttered something that you couldn't understand. "What was that, Buck?"
"Nothing."
"Tell meeeeeeeeee!" you joked.
"Well, um... I, uh, said... actuallyitwasnoproblem."
"Bucky! A schoolgirl crush?" you teased. He stayed quiet and you could almost fell him blushing. "Actually, I've no room to speak. Come into view. Please?" He walked over to chair and sat down where you could see him. "You. Me. Dinner? Not tonight though, unless you're good hanging out with a non-blind girl who's wearing sunglasses."
He looked at you, confused. "Wait, you-"
"James Buchanan Barnes, you are one of the funniest, most handsome, kind of insane guys I've ever met. I like that. I like you," you rambled, though you knew what you were saying. "Um... Wow. Thanks? I... I honestly don't know what to say. I like you, too? Wait, yeah, I'll say that. I like you t-"
"Shh... Don't say anything. Make a quiet exit and I'll see you tomorrow."
"You're so weird." He rolled his eyes, but still did it.
