Mizuki Natsuno is the least popular member of Melty Strawberry, an idol group celebrated across the country. Koichi Okuta is her most devoted fan, always throwing himself completely into supporting her. Fans rarely get close to their idols offstage, but through a string of circumstances Mizuki ends up living with Koichi in his own home. She tells him that if he can truly make her the Center, the two of them can get married. Koichi vows to do exactly that, and an unusual partnership between fan and idol begins as they work together to lift Mizuki out of obscurity and into stardom. Expect a romantic drama built around that unlikely arrangement.
