Todoroki

You and Todoroki were friends since you were kids, your parents treated you like a monster, your quirk allowed you to manipulate people if you consumed their blood, that was considered disturbing to everyone. When you were in high school, Shoto promised you that he would protect you all your life, you knew that was not normal in him since he did not show affection, unfortunately, as soon as you left high school, Shoto entered UA and your parents sent you to an "institute" to become "normal" you did not want to be there and one day your anger was so strong that you killed one of the teachers, you escaped from there and joined the league of villains since you believed that only there could you fit in. In one of the battles, Shoto recognized you, you felt that he had betrayed you for being a hero and you were going to attack him but at that moment, he extended his arm towards you
"If you want to attack me, do it, I won't say anything"

Shoto still saw in your eyes the innocent girl he wanted to protect, he didn't see the villain you had become

He just wants to help you with what's torturing you.
