Kana, who was dating Koji before marriage, used to work at a brothel, but of course she didn't tell Koji about it and planned to keep it a secret until she died. Kana, who came to greet Koji's father, didn't know his father's face because he only talked to him on the phone. From today on, I came to talk about working in Koji's hometown after marriage and living together until the job was stable, but I didn't think that my father-in-law was a customer from the past and the worst man.
