Σ  Chen is the school's math genius and great honour. Yixing is wondering why he even tries. He at math, he never understand any of the things that makes a beautiful laugh roll from the mouth he wants to have for himself, and why he's trying so hard at something he'll never be good at when he could be dancing and taking pin wheels on the grass outside.

The chapter titles are utterly nerdy and getting harder to come up with (they all equal the number of the chapter).
