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