Yui, a married woman who attended the alumni association but had difficulty returning home due to a car breakdown. She was worried about her ex-boyfriend, Satoru, and decided to stay, but she lied that she would stay at her "girlfriend's" house so as not to make her husband worry unnecessarily. I go to bed while being attacked by guilt. The two who became sweaty in the room where the air conditioner broke continued to have sex with instinct.
