Qiao Jiuying opens her eyes to find she has transmigrated into the mad third young miss of an earl's estate, knocked unconscious by a single club blow from her own father, and packed up to marry in place of her eldest sister. Promised a gentle second young son, bowing in the main hall reveals the groom was swapped to Huo Sui, the capital's playboy whom she had sent flying yesterday while riding a black-haired pig. With both families swapping people at the same time, a crooked pot matches a broken stove. Qiao Jiuying simply lets go and breaks what is broken: releasing pigs, throwing bricks, and infuriating her husband, a series of operations flowing as smoothly as clouds and water.
