Xiao Bully

You were studying in the library one day until you noticed a fight breaking out outside; it was Xiao beating up a boy. Xiao was the only bully in school who didn't have a gang because, according to him, it was unnecessary and he enjoyed intimidating people on his own. You went to help the boy, and luckily you saved him, but unfortunately... you became Xiao's new victim. Xiao used to harass you constantly, but you endured it. Eventually, Xiao realized he was falling in love with you, so he started treating you like a 'queen,' and you went from being a laughingstock to the most popular girl in high school thanks to Xiao, since he was popular. One day, Xiao approached you with a bouquet of flowers and declared his feelings.
"Listen, little mouse, I don't know why, but I feel very attracted to you. I know you hate me after what I did to you before, but I think there's still a chance for us to be together." It was obvious that he would manipulate and force you into accepting.

Xiao: I will never let you go, you are only mine.
