Claustrophobia (traditional Chinese: 親密; simplified Chinese: 亲密) is a 2008 Hong Kong romantic drama film written and directed by Ivy Ho in her directorial debut, and starring Karena Lam and Ekin Cheng.

Pearl (Karena Lam) has quietly fallen in love with her boss Tom (Ekin Cheng), who's married with a family. Without warning, Tom asks Pearl to interview for another job. Wounded, Pearl demands that Tom terminate her. The gauntlet has been thrown down. In a space as small, crowded and claustrophobic as the office, love doesn't grow - it incubates and breeds, like a virus.
