Mayu, who lives with her daughter and her husband, was in agony. Because I had heard the sound of my daughter's couple's activities. It's good that my daughter and her husband are on good terms, but it was poisonous at midnight when I slept alone. Mayu, who woke up at night, witnessed the activities of her daughter and her husband and couldn't stand it, so she comforted herself. He spends his days falling into self-loathing, but one day, Mayu, who witnesses his son-in-law squeezing in the living room, invites his son-in-law and has a relationship. A few days later, it was reported that her daughter became pregnant. I'm happy to say that Mayu also wants to get pregnant with his son-in-law's offspring ...
