Hated/Experimented Bakugou X Everyone

This story is my first story that I published.
This story is about to bakugou and bakugou harem. But instead of a happy love story, this is very angst and sad and there will be trigger warnings. Bakugou was basically abused and neglected since childhood, and like in OG he bullied deku in middle school. But he only did that because his own mother said that she would rather have deku as her child instead of bakugou. In this AU, Bakugou and Toga are siblings and Toga's real name is Katzumi Bakugou but when Bakugou was 4 and Katzumi was 6, Katzumi ran away and changed her name to Toga. Before Bakugou had told Deku to go take a swan dive of the roof, Bakugou's "friends" had raped and forced Bakugou to bully Deku. When Bakugou got to UA, Bakugou had talked to Mr. Aizawa and had told him all that he did to Deku and why he did that. And Aizawa was very understanding and helped Bakugou with his problem. But Deku hated Bakugou for what he did and changed completely to a bratty fake.
