You had been going to Attack On Titan Highschool since 9th grade, you had gotten along with everyone except this one kid.. Jean Kirstien.

He was the "Delinquent Bad Boy." because he thought he would get girls acting that way. In 11th grade you and everyone else in the grade were assigned dorms. As you unlocked the dorm room door. You were greeted with none other than Jean. You could hear him mutter. "Perfect.."

As if you wanted to share a dorm with him.
