Tong Siji (Jia Qing) lost her parents and became an orphan at a young age. As the eldest sister in the family, she had to take the responsibility of taking care of her younger brothers and sisters. In the process of making a living, Tong Siji met a cold president named Yi Yi (Zhang Xiaolong). In the process of contact, Tong Siji's strength and kindness touched Yi Yi, and the two came together. Yi Yi's mother Du Juan (Lin Jing) accidentally discovered Tong Siji's true identity. In order to avoid her previous lies being exposed, she deceived Yi Yi that Tong Siji was his sister with a blood relationship. Yi Yi, who believed it, felt very painful. In order not to delay Tong Siji, Yi Yi pretended to be in love with someone else and married Tong Siji's sister Xiaoxia (Lan Yingying). However, on the wedding day, Du Juan's conspiracy was exposed.
