After Mu Tian Xing saves Ling Lie from an assassination attempt, their fates become intertwined. Their parents decide to marry them off, each with different goals. For Ling Lie, his crippled and (seemingly?) mute state means marrying a girl from a powerful family won't make him a threat to the family patriarch. For Mu Tian Xing, an impotent man means her parents never have to worry about her being soiled before they get what they want out of the marriage. Ling Lie is anything but harmless, though, and he doesn't take kindly to being underestimated!
