Six years ago, Shen Yuwei, who was working part-time at a KTV, unexpectedly spent a night with Gu Huai, the president of the Gu Group, and gave birth to a daughter. Years later, Gu Huai had already found his daughter, Gu Niannian, but had never managed to find the woman he had been with that night. Believing his daughter's biological mother to be an irresponsible woman who had abandoned her family and child, he gave up searching for her. That is, until he unexpectedly crossed paths with Shen Yuwei. With his daughter's matchmaking efforts and Shen Yuwei's desire to fend off her family's constant pressure to get married, Gu Huai gradually found himself genuinely falling in love with her. He also discovered that Shen Yuwei had the exact same butterfly-shaped birthmark as the heartless woman he despised.
