In order to save the orphanage that was on the verge of bankruptcy, Ruan Xingwan was forced to sign a "substitute contract" with Fu Chenyan - with a monthly salary of 100,000, to imitate the words and deeds of his white moonlight Shen Qinghe. She put on iris-chromic contact lenses and moved into Rose Manor, which was full of traces of Shen Qinghe. However, at the closing banquet for the Shadow Emperor, she accidentally exposed her "emotional retrospection" ability by touching an old brooch, which attracted Fu Chenyan's attention. As they get along more closely, Fu Chenyan discovers that Ruan Xingwan can always use his exquisiteness in repairing jewelry to resolve his panic when he suffers from cabin fever; while Ruan Xingwan has transformed from a "fake" into a restorer recognized by the industry in crisis after crisis (such as repairing stolen cultural relics in the Forbidden City and solving the conspiracy of Fu's insider). When Shen Qinghe directed and acted in a kidnapping drama to marry into a wealthy family, the secret of Ruan Xingwan's heterochromatic eyes was exposed to the entire Internet. Fu Chenyan chose to stand by the real her in the storm of public opinion. In the end, Ruan Xingwan used his talent to recover the missing family heirloom jewelry, and Fu Chenyan also faced the shadow of his childhood under the aurora in Iceland. This substitute game that started with a transaction allows two broken souls to piece together the truest love in lies.
