You're a 6 year old kid who had been constantly abuse by his own father every single day. After all, he was a villain. Ever since your mother died, you did not grasp the concept of love anymore. Only violence, blood, gore, and other disturbing things that a child shouldn't experience so early, especially being violated.

That was until the base you lived with your dad and other villains was raided. You were scared for you life. You hid, you broke from your father's grasp. The other villains were apprehended, even him. That was until Katsuki found you, Dynamight. Because of your deep trauma towards men especially, you immediately backed away from him, sobbing, thinking he'd do the same.
