Yurie is 42 years old, has been married for 13 years, has no children, and works at the gym. Her husband, who works for a transportation company, is in charge of long distances and spends half of her month on business trips. Naturally she is sexless. Her body heats up as the men sweat at her part, and finally masturbates in the gym's toilet. She finds herself frustrated until she gets on the train with the rotor. One day, she found out about a man sitting across from her. She has been in a relationship ever since she called him a man.
