Lin Wanxing, a 22-year-old fresh graduate, joins the top company "Xingyao Group" with the aura of "genius intern". However, because of his appearance that is 70% similar to the late president Bai Yueguang, he is used as a stand-in by the cold and dignified president Gu Yanshen. From tit-for-tat workplace confrontations to forced "marriage by agreement," the two test each other and grow together in business wars and family struggles. When the truth is revealed, she is not only a substitute, but also the real "starlight" deep in his memory that he has been searching for for ten years. This is an evenly matched love story between two powerful people, as well as a workplace and love legend that redeems each other and shines together.
