Tachibana is a swimsuit idol, admired by everyone at school and treated like a celebrity rather than a friend. Tachibana feels somewhat distant from others, so she tries to be closer and more sociable with her peers. While passing by a classroom, she sees a junior student doing patrol duty alone, and she actively approaches to help. Because she is wearing a short skirt, when she bends down, her underwear becomes visible, making it hard for the boy to look away! Suddenly, Tachibana has an idea; she will let this boy have an intimate encounter with her so they can become friends! From then on, Tachibana acquires many new friends, including two boys who hid in a closet to secretly photograph her changing, a boy who skipped class to masturbate, and a diligent student who is academically gifted... All of them are invited by Tachibana to be her friends!
