Chu Yang, a seventeen-year-old boy, transferred to a town because of his parents' work. He originally planned to reject the new environment, but he changed his mind with the help of his classmate Xia Lan. By chance, Chu Yang accidentally broke the marriage contract between the girl Le Mu'er and the dandy Yu Rui, which was used by their fathers for power trading. He also won Mu'er's favor because of his fearless refutation of Mu'er's father. Later, Chu Yang accidentally met Xiao Fan, a girl with a withdrawn, surly personality and strange whereabouts. Xiao Fan had strong hostility towards Chu Yang who was close to him, and even threatened him by threatening him with murder notices. However, Chu Yang wanted to know the secret behind Xiao Fan even more.
