She transmigrates into a vicious supporting-female character novel written by a hater, becoming the cannon-fodder wife whom her chief councilor husband is destined to avenge himself upon and kill.
With the powerful chief councilor's murderous intent plain to see, Yu Wanwan grabs his leg first, acting meek and obedient as she offers him a tearful divorce agreement to save her life: “H-husband, can't we part on good terms?”
To her surprise, the aloof beauty tears up the agreement and personally raises her to the position of lady of the household. Before long, everyone at court knows that the cold-faced chief councilor has two inviolable boundaries: peace in the realm, and his darling Wanwan.
