Ok, not sure if this is the place to post this but for some reason this memory just came to my head. I remember as a kid once watching a chinese movie where this guy falls in love with a ghost (not chinese ghost story 1,2, or 3). It's a similiar concept only it's set in modern times. Basically, the guy falls in love with this girl who is a ghost, they have fun, then she gets exorcised by some other dude. The main thing I remember is that there was a music box involved somehow with a really cute little melody. Sorry I can't be more specific but the memory of this movie is very vague in my mind but for some reason I want to watch it. Any help would be appreciated. Thanks.
