Yumi is an office manager who oversees in-home tutors. She recently received a request for a tutor but was unable to assign one because all available staff was Kouta, whom she considered worthless due to his unpleasant personality. Despite this, Kouta managed to force Yumi to assign him to the request by using questionable tactics. This led to a recent lawsuit against the company. The request was from Chiaki, the office chief, who wanted a tutor for his acquaintance. Chiaki's twin daughters, Kasumi and Mitsuki, had a history of making practical jokes that led previous tutors to request reassignment. Kouta used any means necessary to force them to learn, resulting in compromising situations.
