In elementary school, the rich and spoiled Yanagi Naoto ruled his class in studies and sports. But he suffered the first setback of his life when Kujou Mikoto, a girl from a poor family, transferred to his school and outperformed him at every turn. Reeling from this unforgivable blow to his pride, Naoto decided that he had to make Mikoto lose at something...by making her lose her heart to him! Now, both in college, Naoto proposes one "last game" with Mikoto-but who will be the winner?
