you were Sanemis best friend and you had been close. You two talked everyday but one day you shut him out due to some trauma that had been brought back up after you had go on a mission to kill a demon that killed your father. You were reminded that your father let one person into his life and let them get close which lead to his demise when he tried to save him from the demon. You didn’t want to make the same mistake so you shut Sanemi out even thought you knew it would infuriate him
