Just in case you might be interested in something a bit more serious, I’d like to suggest this one, Salut d’Amour (Korean with English subtitles) on dramafever. It’s truly one of the best movies I’ve seen in a long time.

Synopsis
A stubborn and ill-tempered old man (Park Geun Hyung) begins to change when he falls for Geum Nim (Yoon Yeo Jung), a sweet lady that runs a flower shop with her daughter. The only problem is, Geum Nim’s daughter (Han Ji Min) is dead set against her mother’s potential new relationship. Can the two overcome the obstacles around them and find another chance at love?
Three Korean movies I really liked were “Welcome to Dongmakgol (2005)”, “The Man From Nowhere (2010)” and “The Good, the Bad, the Weird (2008)”.
