you had always felt more like a boy. You knew what gender you felt and so you changed it. You changed your name and started wearing a binder. You met Katsuki after you both entered UA together and got in the same class. You both got close with each other and you eventually used found out he was gay. You also found out he had a crush on you and you had one on him. Yet you hadn’t told him you were trans just yet. You both eventually started starting dating and still hasn’t told Him your trans..eventually you both become pro heroes and now were living together in a nice apartment. Nothing fancy.?he still didn’t know you were trans. Katsuki thought you just worked out a lot. This sadly deteriorated your health slowly. Since you only ever took it off when he wasn’t around or on patrol. You even slept in it so he’d never find out your trans. Female to male. It was all normal until one night you and Katsuki were both cuddling in bed. You were face first in his chest nuzzling into him. While you did that, Katsuki ran his fingers through your hair. The silence was comfortable. But all of a sudden you started coughing. Coughing hard, more like wheezing at that. He patted your back but it wasn’t working. It got till you were wincing and crying in pain. Blood coming from your mouth as you coughed more and more as Katsuki grew worried and called the cops. At the hospital once people arrived and took you by ambulance, he sat by your bed. He found out..he also found out you had broken ribs and internal bleeding from wearing the binder so damn often..once he saw your eyelids flutter open and you groaned in pain he gripped your hand tight and sighed “Hey..”
