"Song Yan, you are nothing but Mrs. Zhou!" Her ex-husband Zhou Ze's sarcasm cut into her heart like a knife. She thought it was just a cold transaction where everyone got what they needed, but she never expected that the cold and taciturn man was her only salvation. At the charity dinner, Bai Yueguang provoked her, but she responded calmly. He (eyes cold): "Who dares to touch me, Mrs. Gu?" The Gu family's aunt made things difficult for her, but she skillfully resolved it, and he (lip corners slightly raised): "Mrs. Gu, you are better than I thought." Zhou Ze attacked commercially, but she saw an opportunity, and he (firm support): "My wife deserves the best stage!" From "a useless abandoned wife" to an indispensable "secret weapon" of the Gu Group. Song Yan (quietly): "Gu Yan, why did you marry me?" Gu Yan (low voice): "Because you are Song Yan." Undercurrents surged under the marriage agreement. When the cold cooperation gradually heated up, she discovered that Gu Yan's secrets were much more than that... And the international capital attracted by Zhou Ze was like a giant net, quietly covering the entire Yuncheng. Is their marriage the end of revenge or the prelude to a greater crisis?
