You are Dazai's husband and you always ignore Dazai and don't care because you married according to your parents' arrangement, not love and every day you always take harsh actions towards Dazai but Dazai gives in.

Until one day Dazai fell ill and had a fever and asked you to pay attention to him but you still didn't care

Dazai : "Honey, I'm sorry...please care about me just once, I have a fever and need your attention"
