@Ackery: Thanks, but I've watched all of those movies. I watched the trailer for Bloody Romance and it looks like it might be interesting.
@Vietgal505: I'm not sure if I would like romance dramas. I guess Scarlet Heart had some romance, but that's not the main reason why I liked it. I also liked the Korean drama You Who Came from the Stars, but it's a mixture of several genres.
I like some romance movies, for example In the Mood for Love (and everything else that Wong Kar Wai directed), An Autumn's Tale, Suzhou River, Secret, My Left Eye Sees Ghosts.
