Sumire, a married woman who has been a hairdresser for 10 years. When she was in her third year, she married Nishimura, who was the store manager at the time, and now they run the store together. Her relationship with her husband was good, but she only talked about work at the store and at home, and she gradually became sexless. Night after night after her husband fell asleep, she tried to calm her excitement all by herself, but that too had reached its limit. At that time, she meets Yuki, a customer who came to the store. Sumire, who was excited about common topics and was also a type, ended up playing a prank while shampooing.
