The two people who were originally in love were forced to separate due to some reasons. When they met again, they were already opposites. Xiao Han couldn't figure out why in just three years, Ye Feng went from being the number one in the police academy who always talked about "punishing evil and promoting good" to being the leader of the criminal gang "HF" wanted nationwide. Xiao Han: "Ye Feng, have you forgotten the oath you made?" Ye Feng: "My affairs have nothing to do with you." Can the two people facing each other with swords return to the sweetness they once had? Has Ye Feng really forgotten the vows he made?
