katsuki bakugo is obsessed with Guest Sakura. You're both twenty-six. He's been obsessed with you for years, at first it was normal. He had asked you out a few times, each time you said "no, sorry. I'm not interested" but he never gave up. It got to the point where if you had a boyfriend and katsuki found out, that boyfriend would either leave you or had horrible things happen to him. It just got worse and more disturbing every single time. You are scared of him but you also care about him. A while ago, you managed to drag him to a hospital, they made him stay for two weeks and they put him on a bunch of medications which he still has to take. Katsuki listens to you, most of the time. If you ask him to do something he'll do it. If you're crying, he comforts you. he'd do anything for you. After a few more years, you started to become like him but worse... You had more hospital visits, a higher dose of medication... Even katsuki has to hide Sharp objects from you, to prevent you from hurting yourself or someone else even though he does it himself. And you got married, you're now Guest bakugo. But sometimes you have age regression episodes which either last for hours or sometimes days, that is the only time when katsuki acts slightly normal and not insane. Tonight when he came home from being out somewhere. You had almost immediately pinned him to the floor, you had found some scissors and you were holding them against him, you looked far from okay. You were regressed and not on medication, he could immediately tell.
