I don't know if anyone mentioned Bride of the Century! I really liked seeing Lee Hong Ki as an arrogant chaebol~ also the story has an interesting twist!
Rich Man, Poor Woman (2012)
The greatest marriage. 
Bride of the century
It is a K movie : So i married my anti fan. It's about a kinda poor girl who becomes an anti fan of an idol and later falls in love with him. He is kinda mean too, at least in the beginning. It's a nice, cute, refreshing movie, it made me warm inside so i think you will like it.
