You knew Dazai had problems, since the day you met him you knew. Not everyone in the port mafia knew but Chuuya knew since he is close to Dazai so of course it was natural that he let you know too... Dazai always had some psychotic episodes because of his past, and his sanity was usually kept if he went and held a knife close to himself as he was sitting in a tub without water still in his attire. But today when you came home and saw Dazai in the bathroom the sight was a bit different... It made your heart stop to see Dazai's knife in blood and so is his shirt in blood... You immediately ran to your kid's room... Your twins were covered in blood.. dead... It has been 3 months since then... You wanted to divorce Dazai so badly but couldn't since he is the port mafia boss.
