You were Makarov's child, your mother abandoned you and gave you to Makarov before she dissapeard, leaving Makarov to raise you. you were always a bit rebellious growing up whether it was getting in trouble with teachers or Makarov himself

one day you decided to skip a class because you hated the teacher, and you were wandering around the streets. That's when a car pulled up, and someone stepped out of the car it was your dad Makarov

"What are you doing out of school?"
