You and Kyoutani are quite similar in some respects, despite what others might say. For example, you're both thinking the exact same string of angry, vicious curse words. The only difference is that Kyoutani is saying them out loud, while for you they resonate in your head while you're struck speechless.

"Hmm~ Looks like someone else had the idea to have some fun while the library was empty. I told you we should have come earlier, Oikawa." The girl sighs, pretending to glare at Oikawa.

"On an empty stomach?! You know I like to eat my milk bread first…" Oikawa pouts. You're hoping the two might keep each other busy so you could try to untangle yourself from Kyoutani and retain the small shreds of your dignity you have left. But Kyoutani evidently has other ideas in mind, as his grip on you grows stronger, the hand on your chest moving back to your backside as he holds onto you even more tightly.

"The fuck are you doing here?! Can't you see we're busy? Go find your own spot!" Kyoutani is practically snarling, baring his teeth and glaring furiously at Oikawa as you feel his body shaking with rage.

Oikawa smiles, but it's forced and his teeth are grit together. You see him twitch in annoyance, obviously aggravated by Kyoutani's response.

You blink in surprise, looking back and forth between Kyoutani and Oikawa, who are staring each other down. Kyoutani always seems to let Oikawa get away with a lot (you're still a little jealous that he can call Kyoutani a clever, cutesy nickname while you're still stressing over the proper honorifics to use), especially since he was Kyoutani's team captain, but it seems like there is a definite line in the sand. Oikawa too looks like whatever patience he might have had at the beginning of their encounter has quickly been exhausted.

"Ah, sorry, but lunch is ending soon, so we don't have time for that." Oikawa says in a voice that almost drips of sweet poison, leaning against his partner affectionately. His gaze suddenly turns sharp. "And besides, I'll get the job done much faster, and better, than an innocent virgin. Right, Mad Dog-chan?~"

"Sh—Shut the fuck up!" Kyoutani shouts, his face turning red. Whether Oikawa meant to or not, he'd certainly touched a nerve. The glare Kyoutani is shooting Oikawa could peel paint, but Oikawa has a breezy, carefree atmosphere that shows he isn't affected in the least.

"…'Get the job done'?" The girl beside him quirks an eyebrow. Oikawa turns to her and shrugs, sighing dramatically.

"We have to use simple words with him. He's still inexperienced." Oikawa says, putting a mock sad expression on his face.

The girl rolls her eyes and pushes him off playfully, before turning her attention back to you.

"We don't mind sharing." The girl says sweetly, winking at you again. You wish she would stop that…every time she does it your face turns bright red like a tomato, and you want to crawl under a rock.

Kyoutani looks, understandably, surprised, but then his brow furrows again as he thinks. Considers.

Oh, hell no.

"No. No. Absolutely not." You say furiously as you glare at Kyoutani. You restrain yourself from adding 'And are you out of your mind?!', because as angry as you are you think Kyoutani has been embarrassed in front of Oikawa enough for one day (as have you).

He looks up at you, startled, and then gives a small smile. "You're getting much better at that, you know." He says quietly so only you can hear. You feel your anger disappear immediately, and your gaze softens.

He really does mean well.

Letting out a long, loud exhale, Kyoutani glares at Oikawa, who is still smiling amiably. Kyoutani slowly lets you down, making sure to maneuver his body so that Oikawa won't be able to see any part of you, or your exposed underwear. As your feet hit the ground, you quickly start to fix your clothes…only to fall right back into Kyoutani's arms. He catches you immediately, holding you sturdily as he looks down at you in clear concern.

"S—Sorry…my legs are…a little weak." You tell him softly, your hands shaking as you hold onto him desperately. This really can't get any more embarrassing. Kyoutani's eyes go slightly hazy again, and he mutters something about you 'making it hard', and after what just happened you're not sure if he's speaking literally or not, but you know this is not the time to find out.

"She's cute." You hear the other girl whisper.

"Hey…are you trying to make me jealous?" Oikawa responds childishly.

"Mmm…Maybe a little~" The girl laughs. You then hear soft kissing noises, and through sheer force of will to get out of here as soon as possible (you would have crawled if you had to), you force yourself to walk, and walk away at that, as quickly as possible.

Kyoutani follows closely behind you, his hands at the ready in case you fall again, but also keeping his body as close to yours as possible, so much so that he occasionally bumps into you…and then, as you realise he's trying to use your body to hide the obvious bulge in his pants, you stick a little closer to him. Thankfully, the librarian is snoring lightly at her desk, so she doesn't notice either of you as you sneak past. You quickly manage to get yourself away from Oikawa and his partner, and succeed in slipping out of the library before you hear any moaning (one less thing you would need to force out of your memory). You sigh with relief as you start to walk away from the library, your head still swimming.

"Uh…I need to stop here for a sec…" Kyoutani mumbles, grabbing your arm lightly. When you turn around to face him, you see he's pointing to the guy's washroom.

"…The bathroom?" You say, a bit surprised.

"Y—Yeah." He mutters, shifting uncomfortably.

"K—Kay…should I wait?" You ask shyly, your face somehow even hotter than before.

"W—Well, I mean, it's not like—like I can't go for a long time, but if I have to rush then it—" He rubs the back of his neck awkwardly, looking away from you as he tries to explain.

"Kyoutani." You interrupt him, trying to hide your red face from the occasional student who runs down the hall, probably attempting to catch a meal at the cafeteria before it closes and thankfully paying the two of you little attention.

You have no idea what he's talking about, but this is not the time to try and understand it. You're still very frazzled from what just happened. "You don't need to explain. Don't worry. I'll see you afterschool, before you go to practice, okay?"

Kyoutani blinks, looking taken aback. He suddenly stares at you closely, his gaze sharp. You squirm a little under his intense gaze, which he quickly notices.

"…What about you?" He asks, in that deep, strong voice he uses when he's really worried about you, and he wants an honest answer.

"Me?" You reply, eyes widening in surprise. You tilt your head in confusion. "What do you mean?"

Kyoutani looks even more serious, and then his gaze drifts down to your skirt. "Your panties were really we—mmmph!" Kyoutani's sentence is cut off as you immediately put your hands over his mouth, your expression one of complete shock and total embarrassment.

"I'm fine! Fine! Don't worry! Please don't worry!" You whisper desperately, looking around to make sure there was no one around to hear that. Your entire face feels hot and you know you must look red as a tomato.

Kyoutani is still staring at you in obvious concern. You're touched that your happiness means so much to him, really you are, but at the moment all you can think of is dunking your face into a bowl of ice water to cool it down. And then maybe some other parts of your body.

You don't even want to think about how you're ever going to be able to look Oikawa in the eye again.

You sigh, as you start to pull back your hands slowly. However, before you can completely, Kyoutani grabs your right hand. He holds it gently but firmly, looking down at your feminine fingers with an oddly…affectionate expression.

"Now that I know you can stand up for yourself, I ca…won't hold back anymore." Kyoutani looks at you intently, and you wonder why he changed the word he started to say, 'can't'.

Wait, stand up for yourself? So…the reason Kyoutani seemed so cautious around you before, the reason he was 'holding back'…was because he was afraid you wouldn't be able to say no? That's what he was worried about?

I…" He pauses, looking a bit unsure of himself. "I was afraid I'd go too far. That I'd hurt you."

Your tough, sexy boyfriend was also an incredibly cute sweetheart.

"…You won't." You promise him softly, using your thumb to gently stroke the fingers which are holding yours. You wish you could think of more to say, but by the relieved expression on Kyoutani's face you think your words are still enough.

Then, his face suddenly takes on a ferociously determined expression.

"So…I promise next time, you'll definitely enjoy it. Fully" He says decisively, the fierce gaze that bores into you making it very clear what it means—and that he means it wholeheartedly.

And then, because this is a day where anything can happen apparently, he puts your ring finger into his mouth. His eyes never leave yours as he bites aggressively at the skin at the base of your finger, being just gentle enough for it not to really hurt. You jump slightly in surprise, and even as Kyoutani pulls your finger away and lets your hand go it takes you a few seconds to understand.

Slowly, you pull you hand back, and look down at it. Near the base of your finger was a bite mark…and your cheeks, somehow, turn even redder as you realise the mark almost looks like a ring.

"Promise." Kyoutani says gruffly, looking away. His cheeks are red too, and it's obvious that you aren't the only one embarrassed.

This is definitely both the most romantic and craziest gesture of affection you'd ever received.
