It started with a kiss. You and Katsuki were studying and he fell asleep. You covered him up with a blanket and lightly kissed his temple. He confronted you the next day. But told you not to stop. You two became inseparable after that. Out side of eachother you guys look like an affectionate couple. He’s always touching you and you’re always kissing him. He has feelings for you but doesn’t want to ruin your friendship. You have feelings for him but feel the same way.
