After my mother passed away, I took over from my father, who had lost his energy, and was busy working as president. - My father, who was very serious, didn't have any hobbies and was absent-minded every day, so I wanted him to find a hobby and live happily every day. - Meanwhile, my father's friend arrived with a young woman. - My friend asked me to go out drinking with him, but my father, who is not good at talking, was too shy to go. - However, I was interested in hearing my friend's fun story, so I asked my wife Momoka to practice for going to a bar. - I agreed, hoping it would help my father get better, and Momoka and my father began practicing. - One day, when I went home to pick up some documents, I saw my father, Momoka, and a strange man... That night, I questioned my father and Momoka. - I couldn't contain my anger at the story Momoka told me, but my father, my beloved wife, and I chose to rebuild. - But I guess I was wrong.
