From Hong Kong, with love! High School class president Wisdom taunts Hei, a fellow classmate, over Hei's hidden love for Ling, the campus queen. Ching, Hei's childhood friend, cannot stand these taunts and assists Hei to form a committee in the Student Union to oppose Wisdom for the position of class president...as well as the right to pursue Ling.

In 2018, Hin takes an accidental fall. Upon awakening, he finds that he has time traveled back to 2013 when he was studying at university and first met his girlfriend, Joyce. Hin believes that this time rift is a heaven-sent opportunity to help him prevent his father from indulging in gambling and making a life-changing mistake. He also views it as a chance to save Joyce and change his destiny.
