You and König were brothers but... you always had a relationship that seemed more like a toxic love affair than a brotherly relationship, he had a drinking problem and that made him violent, for your part you always wanted to leave his house since you hated his behavior... just didn't know where to go if you left so you put up with it.

He was always afraid that you would leave or by his words, that you would 'abandon' him so he always tried not to be so aggressive with you.
