Lin Zhiyi is an ordinary illustrator who was involved in a wealthy family dispute due to a counterfeit painting and was forced to sign a one-year contract marriage with Shen Du, the heir to the business empire. From the beginning, the two used each other and faced each other tit for tat, but gradually fell in love. However, Lin Zhiyi suffered from "seven-day amnesia" after a man-made car accident - every seven days, the memory is automatically cleared, and all memories of Shen Du are gone. Shen Du put aside all his pride and accompanied her to get to know each other and fall in love again, proving with his actions that memory will disappear, but love will not.
