Daisuke Ichijyo, a teacher overseeing the "Career Dramatic Practice" program, guides students through role-playing exercises to explore future professions. However, these simulations quickly spiral into erotic encounters, starting with his cousin Nao in a nursing scenario and continuing with a temple maiden role-play with Mitsugu. The boundary between practice and passion further blurs when his colleague, Touko-sensei, decides to participate in a forbidden teacher-student fantasy.
After an intimate encounter with Nao, who surprises him in a provocative apron, Daisuke finds himself caught between her and Mitsugu, a childhood acquaintance claiming to be his destined bride. In a surreal turn of events involving roleplay as a stewardess and a maid, Daisuke indulges in the desires of both women, ultimately deciding that he cannot choose just one.
