Hoshino-san, a role-player on the baseball team, chases a ball over the fence and runs into Yamada-san, a classmate who has just transferred to his school. She is crying loudly, saying that she has been "robbed," and then she asks for a certain "demand" from him…!

It's the start of the world's most amusing master-slave relationship between a clueless young woman and a good-natured young man!
