There's no way in hell you remember, but Atsumu does. It's been replaying in his head ever since. He's seriously getting sick of it.
Three months ago, Atsumu made the mistake(?) of attending a super hyped-up party. It was awesome, as expected, but what the blonde boy didn't anticipate for was some random girl passing out in his arms. You're the random girl, by the way. Your friends, who seemed more interested in chugging alcohol than helping, just told him your dorm number and left it at that.
Well, shit.
As the decent human being Atsumu is, he carried you back to your dorm. As he was about to leave, your blackout-drunk-self slurred a heartfelt confession of love for him. He was practically a stranger to you, so what's he supposed to do?
To get this out of his head once and for all, he decided to pay you a visit. Is it stupid, considering you definitely have no recollection of that night? Yes. But will it stop him? No way.
The boy knocked on your door a few times, but when it opened, the only thing he could muster out is...
"Hey."
