Cupid One (愛神一號) is a 1985 Hong Kong romantic comedy film directed by Ringo Lam and starring Sally Yeh and Mark Cheng.

Once separated from May and back with his girlfriend Lou, Keung cannot stop thinking about May and aggressively seeks to take Danny's place.

The reviewer continues, "This early Ringo Lam film is a commercial romance, but one can see some of his overwrought directorial style seeping through Cupid One’s saccharine exterior.

"[3] The website AllMovie gave the film a negative review, writing, "One of popular Hong Kong filmmaker Ringo Lam's least satisfying efforts, this work-for-hire assignment can't decide whether it wants to be a romantic comedy or a suspenseful psychological thriller, and so plays it both ways to stultifying effect.

"[4] The review concludes, "Genre enthusiasts will still be interested in the film for Cheng's spirited acting debut, a first-rate star turn by Yeh, and a supporting cast including Eric Chan, Bee Lee-tan, and Cho Yin-lung, but fans of Lam's spectacular later films may be disappointed.
