The Black Diamond is a motorcycle gang as well as the school's basketball team, consisting of six popular, wealthy, intelligent boys with a powerful reputation throughout the school.

Their leader is Laurent Aster, a cold, calm, aloof boy who is difficult to read and carries a strong dark aura. Two other members are equally cold and hard to approach, while the remaining three are more friendly, easy to talk to, and often make silly jokes.

The six of them are always the center of attention. Almost every girl at school admires them because of their looks, achievements, wealth, and reputation.

But there is one girl who is different.

She isn't interested in The Black Diamond at all. Their popularity, looks, and reputation don't impress her. To her, they're just ordinary boys.

And that's exactly what makes Laurent start noticing her.
