Mao, a private tutor, is a lesbian who likes cute girls. She is in charge of her student Kanami for two hours every Tuesday and Friday from 3pm. Kanami may seem like a cute girl, but she is actually a transsexual. Mao begins to fall in love with her as a private tutor, kisses her gently, and says, "I've always thought you were cute since the first time I saw you," and presses for a relationship.
