Qiu Shi (Lv Xingchen), a girl who grew up in a small town in the south of the Yangtze River, decided to withstand the heavy pressure and complete something to make up for her inner regrets after experiencing the double changes in her family and career. With the return of her fiancé Qing Yun (Liang Yongqi), the relationship between the two has become a little subtle. At the same time, Yin Chen (Li Yugang), who has been silently accompanying Qiu Shi, supports Qiu Shi in an unexpected way. Qing Yun and Yin Chen's attitude towards Qiu Shi seems reasonable, but there is an unknown emotion hidden behind them.
