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. On a hotel bed, under the influence of the drug, Xue found himself fixated on He’s handsome face and grabbed his collar, ordering him to help. He narrowed his eyes and personally helped him through the effects of the drug, leaving Xiao Xue utterly overwhelmed. The next day, Xue, sore and furious, lashed out at He, throwing punches and kicks, only to end up injuring himself and landing in the hospital. And just like that, the grudge between them grew even deeper.
