They are a pair of girls who have known each other since high school. We should be so good to each other that we will never leave each other. Song Chenghuan's mother left when she was eight years old, and her father raised her alone. She had an active personality but was weak and kind-hearted. Shen Qingzhi is a girl with a soft appearance but a shrewd heart. The story between the two of them slowly unfolded after meeting Gu Jiaming. Qingzhi fell in love with Jiaming at first sight, but was shy and found it difficult to speak. Cheng Huan helped her and invited Gu Jiaming to have dinner with her. But because of an accidental fight between girls, she got closer to Jiaming and gradually fell in love with him. Qing Zhi's resentment increased day by day because of Cheng Huan's dissociation. She felt that Cheng Huan was beyond her control and could not bring effective results for herself. She tried to take advantage of their friendship and persuaded Cheng Huan to give up. But Jiaming's love for Chenghuan made the latter hesitate and trapped. In the end, Qingzhi's wish failed to come true.
Liang Wenze, the owner of the restaurant where Cheng Huan works, also likes Cheng Huan. He hopes that she will allow Qing Zhi to start making plans to separate Jiaming and Cheng Huan.

She sets out to break the lie and discovers that Jiaming is completely innocent. In addition to heartache and joy, she found Jiaming and hugged him. But Qingzhi's destructive behavior will not stop. She put Cheng Huan in a state of panic and pain. But Liang Wenze, who loved Cheng Huan, finally helped Cheng Huan and got her out of the predicament. But Qing Zhi, who was extremely crazy, lost her mind and even tried to kill Cheng Huan with her car. . . . .
