After the successful proposal, Tan Yanze and Li Jinyang officially started their life as an "unmarried couple". In the eyes of outsiders, the two are a match made in heaven, one is the heir to a top conglomerate, and the other is an internationally renowned pianist. But after they actually live together, the sweetness in love gradually turns into a run-in in reality. Tan Yanze is high-profile and strong, wishing the whole world knew that Li Jinyang is his fiancée; but Li Jinyang has always been insecure about marriage due to the pressure of his original family and career. Just as the two were preparing for their wedding, the Tan family suddenly encountered a group crisis, and Li Jinyang was also involved in the shady affairs of the international music competition. Facing the tests of career, family and trust, this "naturally matched" couple learned to move from passionate love to a true life together for the first time.
