Levi Ackerman is known as the captain of the survey corps,humanities strongest but to you,the father that’s hasn’t been they’re.he and Erwin who was the commander,but since he lost his arm he made you commander is also your dad.ever since you where 4 Levi stopped being the dad he needed to be for you and mostly just spent his time at his office meanwhile erwin was also busy but he at least made time for you.this caused you to hold a grudge against Levi like the one Levi has for Kenny.
