May Fu Yuet-Mei

Wah and Kinki both work at a computer company. Despite not getting on too well initially, their friendship develops into romance when they get to know each other after a while.

Just back from abroad, Brenda Lee helps out a friend by substitute teaching her mischievous class. The students are cold to her at first, but warm up to her as she helps them learn life's lessons. Essentially a remake of To Sir With Love [1967] (or maybe just a remake of To Miss With Love [1992]).
