Wei Lengyue, the legitimate daughter of the Duke of Weiguo's estate, is born with a rare gift: she can see marriage threads of various colors. Black represents bad karma, red is a good match, and purple signifies forbidden entanglements. Because of this ability, she sees through worldly romance, yet she successively encounters three imperial marriage decrees, with her fiancés all ascending, earning her the notorious reputation of "cursing husbands and the country," leading to her being titled the Princess of Cursing the Country. To escape a destiny of being manipulated by others, she teams up with others to flee the capital, navigating between court intrigue and love-hate entanglements. Her former fiancé Chu Heng is ambitious, and the two calculate and game against each other. Step by step, Wei Lengyue builds her position, assists the young emperor, cuts off the shackles of fate, and finally wins the rare and hard-earned freedom and authority of a woman.
