Love Undercover

Kuen, a rookie cop who flunked every single important test as a cadet. However, Hong Kong needs cops so she graduates anyway. Sentenced to the Lost Property Department, Kuen can only gossip with her co-workers and lust after hunk cop Hung (Raymond Wong Ho-Yin). However, Kuen gets her chance pretty quick. The Serious Crime Unit picks her for minor undercover work because she has no family, boyfriend or dog, and wouldn't be missed if the target decides to off her. (mydramalist.com)
