Originated from Hunan, China, Zhang Yi Xing has been quite an odd boy as a child. Everybody tried to make friends with him but he didn't want to. Living without the disturbance of friends, Yixing grew to be an intelligent person, yet awful social skills. His only dream is to become a successful battle commander one day. But his parents weren't happy.

Yixing has a cruel personality. He can be really harsh towards others. That's way befriending him is not that easy as you think. Strangely, he is sensitive with his emotions. One small threat can make him hate you for an eternity. He also has perfectly polished gears in his brain so he has a possible chance of scoring tests. But sometimes he would forget and forgetting means he'll make a big mistake.
