Last Game Vol. 1 (manga)

In elementary school, the rich and spoiled Yanagi Naoto was known for excelling in both studies and sports. But then he suffered the first setback of his life when Kujou Mikoto, a girl from a poor family, transferred to his school and performed better than Naoto 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, which he could then break! Now that they're both in college, will Naoto finally be able to win Mikoto's affections--or will he lose this final game with her?
