Synopsis
Yumi works as an office manager for a company that provides in-home tutors. One day, she receives a tutoring request, but the only available staff member is Kouta, whom Yumi considers useless due to his unpleasant personality. Kouta finds out about her opinion and forces Yumi to assign him to the job through dishonest methods, as his track record shows he always completes his assignments. Unfortunately, this means he uses any tactic necessary, which recently resulted in a lawsuit against the company. The request is to teach an acquaintance of Chiaki, the office chief, whose beautiful twin daughters, Kasumi and Mitsuki, have a suspicious history: all previous tutors asked to be reassigned after the twins pulled all kinds of pranks to drive them away. Kouta employs whatever compromising trick he can to force the twins to learn.
