Fukada Rei is a cute but up-tight third year high school student, one of the only girls her age without a boyfriend. One day, someone stops her while she was walking to class and asks to take her picture. Rei is confused, but says yes. He takes the picture, and when Rei asks why he tells her her underwear is completely showing. He says he'll delete it later, but only if they meet again at the same place at lunch. Afraid that he'll show it to her class mates, Rei agrees, and every day afterward she meets him for lunch. But what will Rei do when he confesses to her–and she realizes she loves him, too?
