Lin Yue has a reserved and gentle personality. On her first day at Qinghe High School, she fell in love with the handsome Su Ran at first sight. Su Ran is bright and cheerful, but always merciful. Not long after she entered school, she set off a "whirlwind of flirting with girls" on campus.
Occasionally, Su Ran flirted with Lin Yue's best friend, and had an affair with her best friend Bai Yueguang. After getting together with Bai Yueguang, there were constant emotional ups and downs, and Bai Yueguang left due to lack of security. During this time, the relationship between Su Ran and Lin Yue was complicated. Although she regarded her as a good friend, they had many intimate behaviors, and the two were ambiguous.
After several twists and turns, Su Ran found Bai Yueguang, but by mistake, Bai Yueguang left again. Deeply hit, Su Ran took over her mother's business, but encountered a company crisis. Lin Yue, who had been silently accompanying him, stepped forward to help him tide over the difficulties. The two gradually fell in love during the struggle and fell in love sweetly for two years.
However, just when the two were about to get married, Su Ran and Bai Yueguang reunited unexpectedly, and their old relationship rekindled. Su Ran abandoned the pregnant Lin Yue and wanted to renew her relationship with Bai Yueguang. Lin Yue, who has always been forbearing, will not compromise this time. How will she defend her dignity and love? Where will this twists and turns of emotional entanglement ultimately lead?
