I am a college student aiming for professional instructor. By the time the school begins its summer vacation, I was asked to be a part-time trainer in the gym. The contact person is Mao, a cousin who runs a fitness gym. It has been several years since we last contacted each other. So, I was supposed to start my part time job by living in Mao-chan's apartment. As naturally swept that away, I became the exclusive trainer for female members. Really!? Because of the trauma of the past, I do not get along with women, My older sister cousin, Mao seems to have prepared that solution so that I can overcome it... Some women have a very weak-willed, others are rebellious women. Can I respond to their expectation to become an ideal figure? Although I do not get along well with women yet, can I overcome myself!!??
