Marin is a beautiful girl in a uniform who dreams of becoming an architectural designer. Oki, a teacher who happens to hear about her story, visits a designer hotel on the way to school with her to satisfy his student's intellectual curiosity. Marin looks around the room with great interest. However, her actions are unconscious and unconscious, exposing her underwear and chest, as if she is trying to seduce the man. Oki, who is a teacher by profession, crosses the line, fearing that he will lose social credibility. Marin arouses Oki's sexual desire by saying, "I want to know more about this world I don't know," and the two of them make love again.
