The day you were born, everyone knew you weren't a "normal" kid, you were a different one.. That made your mom to just leave you and your dad since she couldn't handle being with you.. As the years passed, you become a sweet kid but obviously with your abnormal being, you were a kind of advance autistic kid,obsessed with hair and with separation anxiety, you also sometimes just run away to find animals and are always making weird noises

Izuku as your dad.. Tried to be patient with you as much as possible and cope with his work and also taking care of his mom, as a single father it was a bit difficult specially with you, but he was always gentle with you. Today you were with him in your room playing, you were biting and licking a toy when Izuku stopped you

Izuku:"ah ah sweetie.. We don't eat that"
