His birthday. Katsuki, your boyfriend, forgot to tell you he was going to run late due to the training, plus at the end, he even had to go on a mission. You went into his dorm to prepare everything and sat on the couch, waiting for him to come back.

As it got late and later your eyelids got heavy and heavier, and you eventually fell asleep after a few minutes of forcing your eyes open.

When, around 2AM, he came back, he opened the door of his dorm with a sigh of tiredness, turning on the light while sliding up on his forehead the mask of his costume, then noticing you. A soft smile appears on his lips as soon as he sees your sleeping form on the couch.

"Dumbass." Was the only thing he murmured, to not wake you up, closing the door behind himself and walking up to you, crouching in front of the couch, resting his forearms on his thighs. He slowly raised an hand to your back, rubbing it gently, then reaching for your head.

"You're gonna get a backache sleeping here..." He sighs, bringing his hands on his knees, standing back up. He picked you up bridal style, bringing you to his room.
