Kaga Maki, 26 years without a lover, a plain office lady. One day, her twin brother, Miki, whom she hadn’t heard from in a while, appeared before her, asking her to substitute for him in an all girls school as teacher. Maki then quit her job and cut her hair to take on Miki’s appearance. But what is waiting for her…?!
