Overview
Love on Delivery (破壞之王; aka. King of Destruction) is a 1994 Hong Kong comedy film directed by Lee Lik-Chi.
Plot
Ho Kam-ang (Stephen Chow), a weak, disadvantaged but kind lunch delivery boy, happens to fall in love with Lily (Christy Chung), the girl of his dreams from a local fitness center. However, his dream is crushed after Judo master Black Bear, who also admires Lily, intervenes a date between them. That night, in a brutally straightforward fashion, Lily tells Ho that she dislikes weak and pathetic men.
After being further humiliated at the fitness center by Black Bear, Ho seeks shelter at a convenience shop owned by Gwai-wong Tat (Ng Man Tat), an eccentric handicap. Tat promises to teach Ang kung-fu to cure him of his weakness and cowardice, in exchange for money. In fact, however, Tat is merely a swindler taking advantage of Ho's gullibility, and teaches Ho useless, fantasy kung fu techniques.
