Su Wan, a newly graduated jewelry designer, owes a huge debt due to the failure of her father's investment. She unexpectedly signs a "contract girlfriend" agreement with the indifferent CEO Lu Shiyan. Lu Shiyan needs to stabilize his image to deal with the family inheritance competition, while Su Wan relies on the agreement money to pay off the debt. The jewelry designed by Su Wan can "reflect the true heart", and the cufflinks she customized for Lu Shiyan revealed his hidden tenderness. As they got along, Su Wan gradually fell in love with Lu Shiyan, and Lu Shiyan was also moved by her tenacity and talent. Lu Shiyan's cousin Lu Ziang repeatedly created misunderstandings and stole design drafts in order to seize the inheritance. The two were estranged from the contract to fighting back side by side. Lu Shiyan opened up about his childhood trauma, and Su Wan also helped him consolidate his position. In the end, the contract was terminated, and Lu Shiyan confessed sincerely. The two stayed together under the witness of starlight and jewelry.
