I think this is going to be pretty long, but it should be good since I'm focussing on keeping them in character. If you spot anything you think is OOC, plz plz plz tell me and explain. I'm trying reeeeeeaaaaaally hard so even if it's terrible please be nice.

Loki:

The first time you kissed Loki Laufeyson, he used his magic to create an image for the cameras that he was in his cell reading while you sat there, looking bored.  In fact, you were just inside his cell, the door to it open.

  You pulled away. "I can't-"

  "You mean, you shouldn't." His eyes are full of hurt and desperation and something else you're 99% certain is love. "Y/N. Do you still think I'm a monster?"

  "You are the one in a cage," you point out.

  "So are you, right now," he counters, face serious, no trace of the mischief you've come to know amd reluctantly love. "They can put anyone in a cage, my queen, but only you can make yourself a monster." His gaze is imploring you and you don't know how to say no. "And I don't want to be a monster anymore."

  He sounds so sad, so pleading, that you impulsively throw your arms around him, holding his body close to yours. After a moment's hesitation, he hugs you back. "Okay," you murmur.

  He pulls away and holds you at arms' length. "Okay?" he echoes hopefully. Neither of you are quite sure what the question was but both of you know what okay means.

  You don't even know how you dare to say it. "Okay."

Tony:

He did it the Tony Stark way. Which is to say a random, crazy, possibly drunk and very public way.

  You were watching TV at your room in Stark Tower - it became apparent the day after your arrival that there was no way to get through everything in normal work hours, so you often stay. When suddenly, Tony's face appeared on the screen.

  "Oh, no," you said immediately to yourself. "What has he done? An interview? I didn't schedule an interview..."

  "Oh yeah, that's actually true," he was saying. "I do have a girlfriend right now."

  You were still thinking when the realisation of what he had just said hit you like a train. Oh. Was that disappointment? Don't be ridiculous. You were his assistant, not... You know. But I guess you sort of thought you had a thing. You're being an idiot, Y/N. This is Tony Stark. He talks like that to everyone.

  "Did you hear that, ladies and gentlemen? Who's the lucky lady, then?" The reporter's sickly sweet voice suddenly began to annoy you.

  Tony grinned and leaned back. "Well, her name's Y/N Y/L/N. And she actually didn't know about this until now."

  You stare at the screen in disbelief. Your hand went to your phone and you texted him. Wtf are you doing??

  You realised what would happen a second before it did. On television, right in front of the entire world, Tony's phone vibrated and he read out the text to everyone. You went bright red and glared at him on the TV, before texting him back. Funny that there's a great deal on bright pink paint right now... And all your suits have been left here unattended. What a coincedence.

  You watched with satisfaction as he paled and got up. "I have to go now. See ya!"

Steve:

He was the ultimate gentleman about it, as usual.

  While you were, as usual, talking with him on your park bench, he suddenly said, "Hey, so, um, I was wondering if you'd like to go to dinner with me?"

  You were caught off guard but instantly excited. Your inner fangirl was screaming, Omg omg omg Captain America just asked me out omg omg omg THE Captain America! Steve Rogers! OMG! You said, "Sure, that'd be great!"

  He looked relieved. You suddenly realised he didn't even look like he'd been running at all. "So, um, there's this really nice restaurant over, um, there..."

  You tried to help him out. "That sounds amazing. 7:00?"

  "Seven," he agreed, nodding gratefully.

  You went to the restaurant, which turned out to be just how you liked it - not a fast food place, but not ridiculously fancy either. At the end of the meal, he asked you sweetly and nervously to be his girlfriend, and I think we all know what the answer to that question was.

Clint:

  As you can imagine, this was, to say the least, awkward. Clint was your inseparable best friend, and the fact that you suddenly blushed when he complimented you and he became suddenly over-protective and jealous over you and other guys, actually started to make the two of you grow apart. This was so alien that you didn't know how to deal with it.

  But something happened to reverse that. You were on a hospital bed, pale and lifeless, while Clint paced and the over Avengers attempted to calm him down, only succeeding, as usual, to make him feel worse.

  "It was just a flesh wound," Natasha promised, which would've been convincing if she wasn't biting her lip. She only did that when incredibly worried.

  Bruce looked up. "Actually-"

  Natasha gave him a look, and he shut up.

  "Do not worry, Clint," rumbled Thor. "The Lady Y/N is strong."

  Tony snorted. "That's not what you were saying until she thrashed you in hand-to-hand combat."

  Thor's face filled with anger. "That-"

  "This isn't the time for one of your squabbles," said Steve, glowering at the two of them.

  Clint continued to pace, ignoring the others.

Then a doctor rushed through the doors. "I'm looking for Clinton, Clinton Barton?"

He practically ran over. "Yes?"

"She's allowed one quick visit before she goes into surgery while we prepare the room, and she asked for you."

Clint nodded, and hurried past her, knowing from experience where each department for wounds was. However, he was dismayed to find she wasn't where he'd expected, but in the more serious injuries' area. "Y/N/N?"

You gave him a weak smile, drowsy with the effect of the drugs. "Hi."

"Go out with me?" he asked. Any other time, it would've been crazy, but now - now there might not be any other chances. The idea hurt.

You smile back, stronger this time. "Sure, Katniss."

Bruce:

So, the world didn't end. Yay, and all that. It took a few days, so you had to wait a while for your coffee, but eventually there was a human population to give you it and a café standing where you could get it, so you and Bruce went, partly to escape a very hungover set of Avengers after the celebration party at Stark's.

  "So... How's the, um, science going?" you asked.

  At first he seemed a little hesitant to talk about his work, telling you you'd find it boring, but as he went on he became more and more enthusiastic. Half the time you didn't know what he was talking about, but you knew some stuff, and you just enjoyed his passion for the subject.

  "Can I ask a question?" he said shyly.

  "Um, okay," you reply, hoping desperately that it's not about what he's been discussing for the last five minutes, because you have no idea what he's been discussing for the last five minutes. Something about particles.

  He took a deep breath. "What.... exactly.... is this? Is it like friends going out for a coffee, or, or..." He mumbled something.

  "What?" you say, bemused. [A/N: Isn't that a fun word? Bemused. Beeeeeeeemused. Bemuuuuuuuuuused.]

  He takes another deep breath. "A, sort of, maybe, not exactly, but similar in some ways to, a date?"

  You shrug and try to fight back a bordering-on-manic grin. "I guess you could say that."

Bucky:

You were in a cupboard at the time. A janitor's storage cupboard, smelling strongly of disinfectant, tied up and with duct tape stopping you from speaking.

  Note to self: In future, do not mention the Ice Cream Incident to Natasha Romanoff. Not helpful and potentially life-threatening.

  You can hear a couple of guys, minor field agents, chatting just outside. So you're still on the Helicarrier. You try to bang on the door for help, but you can barely move. Well, it was Natasha. Now you've probably been set back in your therapy with her by several months' work. Dammit.

  "What do you think of the psycho? Dr Y/L/N?" you hear one of the agents say lazily.

  Psycho?! It takes you a moment to realise he means psychologist.

  "Um, have you seen her?" A second man, you think the only other one. "I would not mind a piece of that, my friend."

  Your cheeks go scarlet. How dare they talk about you like that?

  And then you hear a third voice. Bucky????????? "What the hell do you think you're talking about?" You hear a slam and a slight yelp as one of the agents is shoved against a door. You'd forgotten he was allowed out a few hours a day now, and you can't help but feel a warm glow inside that he's defending you.

  "What the **** does it have to do with you, man?" said the other, backing away as he did so.

  You hear the force behind it as Bucky throws the man to the ground and you almost find it in your heart to pity him. Almost. "Y/N is my girl, so don't you ever talk about her like that again!"

  I'm- wait, what? Since when am I his girl?

That, of course, is when a burst of wind screams through the corridor without warning, and the cupboard door swings open.

Pietro:
Y/ = The first half of your name
/N = The second half of your name

"We have got to do this somehow," Wanda stated.

  "The entirety of Midgard is going to collapse if we cannot make this happen!" Thor agreed.

  "We've sorted that, but the question is how are we going to get Y/ietro together?" Natasha cut in angrily.

  Tony looked up from his phone. "Hey! We agreed Pietro/N was the ship name!"

  "Get off your phone, Stark, this is serious," Steve ordered. "Pietro and Y/N just have to be together."

Wanda read over his shoulder. "How to get a superhero and his sister's extremely hot best friend the superspy to fondue?"

"What?" said Tony defensively. "Your idea sucked. I mean, pretending that they asked you to ask them? Pathetic."

Suddenly Clint's voice came in over the earpieces. "Code Y/ietro!"

"We agreed Pietro/N!" hissed Tony angrily.

"Shut up and act natural, Stark!" whispered Natasha.

  You and Pietro walked in. What the Avengers didn't know? You'd both been listening to the entire conversation and laughing your heads off. "We wanted you guys to know-" You made an odd choking sound and covered your face to hide your giggles.

  "That we are now dating," Pietro finished smoothly, and without waiting for a reply the two of you walked out, went out into the corridor, took one look at each other, and burst into laughter at the sounds of celebration coming from your earpieces.

That took a while! Enjoy, ICTOANFYGs!

Btw, none of you have worked out what that means yet... First to do so gets a dedication!
