After falling into the water, Lin Wanwan claims to have transmigrated from ancient times as a favored imperial consort. Relying on her palace-intrigue tactics, she vows to steal Zhou Ting'an, her childhood sweetheart, and take the place of his fiancée, Tang Jinyun. Her schemes escalate one after another: playing the victim, plotting murder in the wilderness, setting traps at the engagement party, faking a pregnancy to force her way in, and fabricating a paternity test. But what she never expected is that Tang Jinyun has already seen through everything. Faced with one deadly scheme after another, this clear-headed and decisive modern woman neither cries nor tolerates the abuse, and she certainly doesn't wait for someone to rescue her. Instead, she fights back with surveillance footage, science, and the law, turning every calculation of the so-called 'thousand-year-old seductive consort' against her. When her obsession with palace intrigue spirals completely out of control, and both the engagement and their lives are put on the line, who is truly the one pulling all the strings?
