Gu Wanqing, CEO of the Gu Group, signs a three-month contract marriage with Lu Chen, a construction worker moving bricks, to fight for her life choices. Getting along, the two gradually build trust from cooperation. Facing the operational pressure of the Gu Group and the test of the Linjiang New Port project, Gu Wanqing stabilizes the company with her ability, and Lu Chen also re-faces the responsibilities of the Nine Heavens Palace he left three years ago. After experiencing career trials and guarding each other, the two learn respect, responsibility, and growth together, finally tearing up the agreement and turning this marriage that started from a promise into true companionship.
