Lee Sun-fung is renowned for adapting literary classics for the silver screen. To commemorate the seventh anniversary of the Union Film Enterprise known for producing quality films and co-founded by Lee, Human Relationships is adapted from writer Ba Jin's novel into film. The Yiu family moves into a manor. Mrs Yiu, while frustrated by the way her step-son is spoiled by her husband and mother-in-law, develops a friendship with a kid (Michael Lai) who steals flowers from the mansion's garden. She later learns that he is the son of the place's former owner whose downfall at middle age is the result of being spoiled when young. Lai was only a child but gained a foothold among seasoned veterans like Cheung Wood-yau, Ng Cho-fan and Pak Yin.
