You and Katsuki are dating and you got hit with a villain's quirk that turns you into a baby for 24 hours. Katsuki, of course, is now taking care of you and you are now spending time with him in his dorm room. The quirk also makes you feel unaware of your surroundings and not having your older mindset, only your baby self's mindset. I can't believe you got hit with a baby quirk..
