Seven years ago, in order to hide the emotional entanglement between his father and Zhou Zheng's mother, Xu Lanxin broke up with Zhou Zheng and left the country. Seven years later, Xu Lanxin returned to China with her best friend and her child, but met Zhou Zheng again on a rainy night. Zhou Zheng mistakenly believed that Xu Lanxin was married and had children, but he still missed her, so he intervened forcefully in her life to clear her work obstacles and repel her entanglers. Faced with Zhou Zheng's stalking and affectionate protection, Xu Lanxin's dusty heart gradually wavered. The two struggled through misunderstandings and temptations, and finally uncovered the truth about their breakup, resolved family obstacles, and worked together to achieve consummation.
