Gu Yanci, the leader of the wealthy Gu family in Jiangcheng, was forced to sign a contract marriage due to a family alliance. However, the bride was Su Yuning, a high school student from a poor family who was tricked by her stepmother and married into the family as a substitute. Relying on scholarships and part-time jobs to survive the poverty-stricken education path, he is extremely self-disciplined and has a clear goal - to escape from his original family and live out his life. An exchange of interests bound the two people, and the prenuptial agreement was clearly written: when it expires in three years, they will not interfere with each other. But no one knows that Gu Yanci looks cynical on the outside but very measured on the inside. He looks like a handsome and prodigal son, but in fact he controls the overall situation. As the business game and family disputes gradually unfolded, the two went from being wary of each other to getting to know each other again, and the rekindling of old feelings quietly grew. The picture of urban life under the realistic background slowly unfolds, including workplace struggle, academic pressure, and the collision of human warmth and class. In this glamorous and cruel city, she made a comeback against the wind, and he was always by her side. The reunion was no accident.
