Makishima Yutaro is told by Asaki Seiichi, a popular guy from the soccer club, "We're a man short, so I just went ahead and included you in this mixer." Furthermore, it turns out that everyone else at the mixer already had a girl he's interested in, so Yutaro is told to take care of the remaining unclaimed woman. But that "remaining" college girl turns out to be Kiraboshi Ayane, the former leader of a wildly popular idol group!? Yutaro's life takes a dramatic turn when he gets together with Kiraboshi Ayane, the former idol who is cute enough to be called a "national treasure." (Source: PASH! Books, translated)
