Ideas of K-Movies to watch?

Hello, 

I'm looking for good K-MOVIES (not drama for the moment because I have to study T_T ). I don't really like horror, thriller or with a sad end. So if possible romance, comedy, historical, action, detective or vampire,... with a good or happy ending. I prefer K-Movies, but I'm also open to other "nationalities" movies.

I really liked those movies: (so you can have an idea of what I like ;-P )

- The Thieves
- Secretly, Greatly
- Company Man 
- Confession of Murder 
- Miss Granny
- The Man From Nowhere 
- The Con Artists
- Grand Heist
- The Pirates

Do you have any ideas?

Thank you in advance =)
