Qian Yunxi, daughter of Guyu State's prime minister, was born with the psychic power, so she has been considered a jinx, and is forced to marry prince Ye Youming. Seeing her so sincere and kind, the proud prince tries every means to show goodwill, but Qian Yunxi takes his action as ill intention, and matches wits with him.
