While caring for her father-in-law at home, Momose Jogasaki obtained her home helper certification. Concerned about her father-in-law's age and anticipating the need for medical care, she decided to acquire more advanced skills by taking a part-time job at Komiya Care Service, located near her home. However, the facility's manager, Koyama, was known within the company as a sexual harassment offender. Unaware of this fact, Momose became Koyama's target and was drawn into various forms of sexual harassment under the guise of caregiving training sessions.
