In this life, gang leader Xue looks down most on people like Third Young Master He: all polished on the outside, successful in every way, always wearing a deadpan expression, yet secretly more scheming than anyone else. Meanwhile, Young Master He despises people like Xue the most: a streetwise punk with a foul mouth, fierce in fights, and so easily moved by the smallest favor that he’d repay it with absolute loyalty. During their four years of university, they were nominal love rivals and true sworn enemies, prone to throwing punches every time they met. They both assumed that after graduation, they would never cross paths again. That is, until news arrived that their mutual “first love” was getting married. Xue, drowning his sorrows in a bar, was accidentally drugged and saved by He, who happened to pass by.
