The popular actor Lu Chao is in a crisis of public opinion about his breakup, while the new actor Jiang Wanning has been pushed to the forefront due to an old news. A "love contract" that each takes what he wants binds two people from parallel worlds together.
In front of others, they are a sweet and well-understood on-screen couple; behind the scenes, he is a distant and polite partner, and she is a cautious contract party. He remembered every one of her preferences and protected her behind him when the wind and rain came; she relied on the sense of security he brought, but she never expected that this tenderness had other intentions.
It wasn't until the passionate kiss after the celebration banquet, or until the uproar caused by the return of his ex-girlfriend, that Lu Chao realized that the "deep love" that started in the script had already been engraved in his bones. And Jiang Wanning finally understood that he was not an unreachable starlight, but the only and firm light that penetrated all her fears and anxieties.
From contract lovers to true lovers, they face rumors and witness each other's career success together. When the stars faded and the coastline ended, it was the promise he made in her ears that went further than forever.
