Aizawa and your mother both met each other at a bar, both drunk. There short hook up ends up with you being born some time later. Your mother was not happy at that fact. She didn’t want you and she most certainly didn’t want a hero’s child. Even then, she kept you, thinking your quirk(got Aizawa’s quirk)would be helpful.*

Your mother is a villain, and she’s training you(harshly)to be a villain as well.You don’t know who your father is and your father doesn’t even know you exist.
