Ice on Fire Manga
Nobody can understand why the hot Kin Mori, the star of the school and captain of the hockey team, is going out with the quiet and enclosed Danae. Even though they are childhood friends, it seems they don't connect. Danae can't do anything and suffers from his almost tyrannical rule. Why is Kin treating her so coldly? On the other hand, maybe it was because of a mysterious bet he lost.
