A 35-year-old wife/Apology for adultery

It has been eight years since Naoya and Minako got married. Minako didn't feel sexual desire, and they were in a sexless condition for a long time. Minako, who was not looked at by her husband and disgusted herself, drank "LOVE HUNTER" which was recommended by Saito, a drug salesman, and slept with a man other than her husband in the living room where she had fallen into desire.
