Inui Seishu and Kokonoi Hajime are a married couple that would always argue about mostly one thing, Akane Seishu, Inui Seishu's older sister. They would always fight because Kokonoi always calls Inui "Akane" sometimes. It irritates Inui and they end up in a quarrel. Inui couldnt take it, but was only still with Kokonoi because he didnt want you to have a single father...
