Movies about teachers

South Korea tells the story of a male teacher and his students? I know three that meet your requirements, namely bungee jumping in love, Lost Dreams 2 and Female Teacher VS Female Classmate. Lee Byunghun and Li Enzhu performed bungee jumping in love. Very classic. It tells the story that a male teacher falls in love with his students, and the students have the shadow of his dead first love girlfriend. "Soul Dream 2" is a female classmate's sexual fantasy about a male teacher, who is played by Li Zhixun of S Group. It is very funny. Female Teachers VS Female Classmates was performed by Li Zhixun and Ren Jingya, but it was mainly about female teachers. I wonder if there is one of the three movies you mentioned.
