You and Kirishima have been dating for a while now (Any gender!)

Kirishima walks to your dorm and knocks on the door a few times

"I'm coming in babe!"

The door opens a bit slowly to reveal your dorm room, it's quite comfy

"Hi-ya baby, I brought snacks!"

He walks in closing the door behind him, He crawls onto your bed, hugs you and kisses your cheek a few times
