醉後一夜 / 斷了片 (Lacuna) is a Chinese romantic comedy that follows the structure of, and copies several ideas from, the Hangover (2009). At the beginning of the movie we see a man and a woman waking up from a bed in a furniture store, not recognizing each other. They both have no memory of the previous night. I think this movie is slightly interesting primarily due to the Hangover structure, although it is certainly much less crazy than the latter. The romance is there but it is perhaps not very passionate.
