The star-studded top actress Jiang Wan is the perfect idol in the eyes of countless fans. Her career is booming, but no one knows that she has long been shackles of marriage. The other end of the shackles is tied to the ever-changing, ruthless and ruthless business giant-Fu Jinheng.
A contractual marriage that began with family interests forcibly bound people from two worlds. In front of others, they are strangers who have nothing to do with each other; behind the scenes, they are "roommates" who live in the same room but are as cold as ice. He gave her the ultimate material and resources, but also gave her profound indifference and alienation.
She abides by the contract, plays the transparent Mrs. Fu, and works hard in the entertainment industry, just to realize her self-worth and to one day completely escape from this cold prison. But when the scandal between her and a popular young student was spreading, he uncontrollably pushed her against the wall for the first time, with a dangerous look in his eyes: "Mrs. Fu, don't forget your identity."
When sincerity quietly collapses in disguise and temptation, when past secrets and calculations gradually surface, how will this marriage that began with a transaction end? Should the song end and everyone go their separate ways, or should he indulge in the starry night and hide the moonlight that belongs only to him?
