Mr. K.K. Ho (starring Vincent WONG), is a leading “star tutor” with remarkable achievements. Lee Lung Kei (starring Hugo NG), the stingy boss and principal of the cram school, regards Mr. Ho as a trump card. Chloe (starring Jennifer YU Heung Ying), a traditional high school teacher, has always tried her best in teaching. Chloe despises K.K.’s teaching methods and refers to them as deviant. The two of them give tit for tat in class. Their conflict leads to K.K.’s appreciation for Chloe. He gives her flowers as an apology, but Chloe never accepts. He finds out Chloe is the daughter of Principal Lee. When she was young, she witnessed her mother being bullied and died by accident.
