Sixteen years ago, Li Doukou's father died in the line of duty, and she was taken home by Lin Chi's father. Li Doukou learns love here, accepts love, and becomes increasingly inseparable from this home and Lin Chi. However, she is taken to another city by her mother who suddenly appears. In her new life, she met Xi Bei, who dared to love and hate, and Xing Lu, who even had a lonely attitude similar to hers, and gradually became Li Doukou's inner demon. And Lin Chi, whom she longed for, also had a new life of her own. The girl named Shen Luan became a thorn in her heart. ——Her childhood friend is getting married, and she is marrying her friend. Li Doukou still couldn't let go of this. So he used Xing Lu as an excuse to maintain his self-esteem and cover up his humbleness of "unrequited love". However, in fact, the camera only needs a slight change to reveal the hidden thoughts of the young man Lin Chi. Li Doukou has always been hidden in his heart.
