Korean dramas to watch with a friend

Hi everyone ;) I've seen a lot of Korean Dramas but I'm gonna travel soon with a friend and I'm looking for some that I could watch (or rewatch) with my friend to introduce her to this universe as she is not at all into asian stuffs. Know that she is a down-to-earth person, and I'd like dramas that are not too dumb, soppy or cheesy... Movies allowed too ! Please give me your ideas ! ;D

So many suggestions and choices thank you ;)
