Keiko Obayashi is studying to become a pharmacist and a star player of the varsity lacrosse team. Happily in love with her boyfriend or that's what she thought, because suddenly, their relationship ends. He was going out with another girl! Crying loudly, Keiko jumps on the first train that comes along. The train takes her to a tiny town in the suburbs. She enters a drugstore at the end of the mall. She begins working there part-time. Meanwhile, the town's middle-aged shop owners stage a surprise attack on the drugstore, its archrival. However, after storming into the drugstore, they are greeted politely by the adorable Keiko and fall in love with her at first sight. Just to win her attention, they try their hand at lacrosse. Keiko volunteers to coach them and begins rigorous practice.
