Hero Tomomi Amagi is coming home late from school due to being on the school's festival committee. He hears someone shout "STOP THIEF!!" before getting smacked by a guy on a motor scooter who was stealing a woman's purse. Tomomi breaks his leg in the process but the thief is stopped. At the hospital, he is told that he must be there for two weeks, which is about the time left before the festival. Head nurse Shizuru Kosaki is very mean and nasty to him, but the nurse in charge of him is a woman he once knew, who is very friendly to him. Can he heal up in time to attend?
