Okay but Sheith college au where Shiro had amazing, athletic,...

He even puts up flyers.
He made it in paint. It's written in comic sans. It's asking if someone had a *really* good time Saturday with a man with a metal arm.
'Are you the winter soldier?' Keith snatches the flyer off the board, 'You put your number on these?' He crushes the paper in his fist.
'Hey! I met me soulmate Saturday, Keith. Have some sympathy.'
'Correction,' Shiro holds up a finger and Keith looks about ready to bite it off, 'I had AMAZING sex.'
'Sure you did, big guy.' Keith rolls his eyes.
'Oh, I did something alright.' Keith mumbles as Shiro smoothes out the wrinkles and pins it back to the board.
'What was that?'
'I played scrabble.'
'I wouldn't call what you did Saturday 'pulling'.' Keith air quotes.
'I did something right.' Shiro grins and nudges his shoulder.
Shiro watches his flyer on the board. A few stop. Some do a double take. A few laugh.
Lance joins them midway through with one of the flyers, laughing, 'What is this?'
Shiro sniffs irritably, 'I'm trying to find Cinderella.' He glances back at his flyer.
'I think you mean cinderfella.' Lance cackles, 'And look no further because - OW!'
Keith is scowling at his coffee like it's personally offended him.
Lance rubs tenderly at his side, 'Mean.'
'Deserved.' Keith growls.
Shiro narrows his eyes, 'Do you two know something?'
He yelps again, his knee hitting the underside of the table.
'Who me?' Lance waves a hand with a loud 'pffft', 'Not me nooo. I did - however - HEAR things that can not be unheard. And let me tell you, your cinderfella is an absolute wild cat in - MOTHER FUCKER -.'
'Lance didn't see shit.' Keith releases it when Lance begs him to let go, 'Because he was leading a conga line through through the house.'
'Nope!' Lance shouts.
'Why does it even matter?' Keith grumbles, 'You can't remember what happened.'
'Oh boy.' Lance croaks.
'I know at some point he was riding me and it was glorious.'
'I need water.' Lance whispers.
'Shut UP.' Keith hisses.
'Anyone who's smart will burn it.' Keith grumbles.
'Your romance bone is broken.' Shiro sighs dramatically.
'Oh I think his bone works perfectly well-OUCH.' Lance takes the punch to his shoulder.
Keith growls at him as he goes.
'Hmm.' Shiro slumps, 'Guess I wait till someone calls me.'
'Well how else will I find him!'
'Why do you want to find him at all? You've slept with plenty of randoms since we met. What makes him so special?'
Keith eyes him warily, 'And what if he doesn't look the way you imagined?'
'I don't care.'
'Does Keith really think I'm that shallow?'
Matt glances over at him, 'Uhh.'
'I have a type. Sure. But -.' He pauses in his steps. Squinting into the distance.
He's not - the best looking dude. But he looks to be on a mission.
'This yours?" The guy asks, waving a wrinkled version of one of Shiro’s flyers.'
'Uh yes?'
Shiro blinks, 'Fuck you?'
'No!' The dude hisses, 'How did you convince him to sleep with you?'
Shiro realizes that this dude isn't his cinderfella. But someone who SAW.
'Crap.' Matt hisses from his left.
'That’s it?" The dude asks increadously, 'I tried to get him to go out with me four times last semester and his bitchy attitude was a serious roadblock.'
Shiro opens his mouth, then closes it, 'Excuse me?'
Too cheerfully.
'Who are you talking about?' Shiro asks.
The dude snaps the paper in the air, 'Keith? Kogane? Yay high? Scowls at everything? Gorgeous as all get out? Sweet peach of an ass?'
Matt slaps his forehead.
'I slept with Keith?' Shiro turns to Matt.
Matt scratches his cheek, 'Uhhh. Maybe?'
'Does Keith know I slept with Keit!?' Shiro shoves his hands into his hair.
'If you so much as breath in his direction, I'll make sure you eat that flyer through a straw.'
'What the fuck man!'
'This is the best day of my life.' Matt exclaims.
'What is wrong with you, dude?' The guy scowls down at where Shiro is wrinkling his polo shirt, 'It's just a piece of ass that you already got!'
'Bzzzzt.' Matt chirps, 'Wrong answer, friend.'
'Whatever man.' He slaps Shiro’s hand away and steps back, 'You're awfully possessive over one fuck at a party. Weirdo.'
Shiro sends him a glare, 'You are not helping.'
Matt types merrily away on his phone.
'What are you doing?' Shiro snatches it, 'Prince Charming has found the glass-are you serious?'
'If you call me cinderfella one more time I'm going to shove a glass slipper down your throat'
Shiro doesn't even fight the smile that response causes.
But it falls just as fast because - fuck. He slept with KEITH.
And he hates that he's remembering that night as he stands in the middle of a walkway with Matt on one side and the horny, disrespectful human garbage disposal on the other.
He got drunk and embarrassed himself and sang at the worst pitch while he dipped his best friend in the middle of a house party dance floor and Keith STILL went upstairs with him and let Shiro - let Shiro -
'Well, evidence suggests you did Keith. Vigorously and enthusiastically.'
'How many people were outside the door?' Shiro asks incredulously.
Matt frowns and starts counting on his fingers.
'Matt!'
'We didn't STAY.'
'Or it could be that you said you loved him in the middle of sex.'
Shiro croaks, 'I did not.'
'Oh. You did.' Matt nods 'I do believe your exact words were 'I've been in love with you for a year. Marry me.'
Matt hums, 'I think that's something you should find out for yourself.'
The Dude scoffs, 'I mean-judging by the sounds he made after-HEY!'
'So sorry.' Lance’s voice sings, 'I thought I saw a bee on your back! My bad.'
Lance holds up his phone, 'I'm your pumpkin, prince charming. Look. I even wore orange.' He waves to his literal pumpkin crop top.
'The fairy godmother.' Matt bows dramatically.
'I don't think that's how Cinderella goes-.' The Dude wrinkles his nose.
'Be quiet.' They all say.
