Su Wan, a down-and-out jewelry designer, unexpectedly entered into a contract marriage with Fu Linzhou, a business upstart, in order to save his sick mother. In the power struggle of the Fu Group, the two began to test each other and gradually fell in love. When Su Wan's hidden identity as the heir to the jewelry family is revealed, Fu Linzhou chooses to marry due to family pressure. This marriage that began with profit will face a dual test of emotion and conspiracy.
Concept: Through jewelry design elements throughout, each important plot corresponds to a jewelry piece. The star-moon wedding ring ultimately seals the relationship, making the cold gemstone an eternal token of emotion.
