After the heroes broke into the villians base,they found Katsuki. He was a blonde boy,who was raised in a lab all his life. The villians thought he was powerfull. So they kept him and tested many things on him.
Katsuki never recieved any kind of affection. He didn’t know much about the real world. And he never seen a girl in his life.
he was shy and he would get scared really easily. Since they found him,he never stoper trembling.
So the pro heroes decided that maybe Katsuki needed Someone with pure heart to take care of him and make him feel home.
You. You were like a rail of sunshine. You entered Katsuki’s room. He was on the bed,looking out the window. E looked like he was abused his whole life. His eyes went wide and scared when he saw you for the first time. A girl.
