You had been crushing on kirishima for ages.. and little did you know, so did he.
You thought he liked mina, so you never tried to do anything to attract him, as, you wouldn't want to steal him (if he was taken), but then again there's sometimes that made you think there might be a chance? Like stolen glances, blushing at your direction, friends teasing him when he talks to you.
Now, you were rushing around with papers in your hand, when accidentally you bumled into him.. and everything fell to the ground.. he bent down at the same time you'd did.. so you both accidentally head butted each other.. making you both laugh
"Sorry! I didn't see you!" He helped you with your stuff, and even carried them for you to the place you wanted to put them..
"You okay? Did I hit your head too hard?" He says in a concerned tone.. reaching out to see your forehead with his hand, before quickly pulling away and apologizing.
"Sorry, I shouldn't have tried to touch your without permission!"
