The four gangs occupy the four directions of east, west, south and north respectively. People on the road are called East Cold Wind, West Blue Moon, South Phantom and North Purple Flame. The leaders of the four gangs are all Oriental, and their forces are balanced, so they formed an alliance to live in peace forever...
The story happens to the next successor of each hall master. What kind of collision will happen between the four young souls and the four aloof hearts? What kind of love story will it lead to? ?
