Ms. Kogiku, who remarried her father 10 years ago, is my mother-in-law. Her cheerful father passed away two years ago, and Kogiku-san, who looked lonely, seems to be doing well now. She has also resumed her cram school which she used to do at home, and she seems like she's finally gone back in time. I'm a little worried about Kogiku-san's health because cram school seems to be busier these days. When she was wondering why she got so busy lately, a shocking fact turned out. It seems that Kogiku-san is giving an obscene class. While thinking that she couldn't believe it, when I looked into her class scene, she found that Mr. Kogiku and her mother-in-law were in trouble.
