Looking for romance k-dramas

Hi! I would like recommendation of k-dramas that can be Drama (Melodrama)/Suspense/Mystery/Action/Fiction but THEY MUST (i'm not mad btw u_u heheh) focus on the ROMANCE of the leads. Something like >>My Love Eun Dong, Angel Eyes, I Miss You, Man From The Stars<<.... I pretty much like when dramas don't have a lot of misunderstandings (like >Fated to Love You<) and the bitch second lead female. I don't mind sad endings, death, leads dont getting together... just, all the way together! Thanks and sorry for being such an ass on my requirements.

Haha oops! I just realized that I totally read that wrong. I thought you had said that you like the bitch second female lead. That's why I recommended the ones I did. >_< lol So sorry!

Ok new list for you. :p

 It's Ok That's Love

Emergency Couple

Doctor Stranger
