In her past life timeline, Zoe Shaw was schemed against by her fiancé Cedric Graham and her younger half-sister. Reincarnated back in time to the engagement banquet, she immediately calls off the engagement on the spot, and enters a contractual marriage with Ethan Graham. The two go from mutually using each other to working side by side to investigate her mother's old case, uncovering years-long conspiracies involving Shaw Group shares, the eldest branch of the Graham family, Mara Cho and other parties. Faced with family betrayal, project power grabs and the truth of the old case, Zoe Shaw takes back her mother's inheritance and regains control of the Shaw Group, while Ethan Graham also lets go of his past grudges. The contractual couple develop genuine feelings for each other amid revenge and mutual protection, eventually choosing to stay together, and complete a full counterattack against fate.
