I'm a guy, so you can't trust my ratings on their looks, but since they're the lead actors they must be good looking. All of these are exactly what you're looking for.
Gaksital is crack, and
Chuno, along with
Team TEN and
Vampire Prosecutor are badass.
Panda,
Cyrano, and
Secret Garden are romantic comedies that pull off the dark past well (although
Panda might have too much fluff for some). I also added
Moon/Sun, even though I didn't rate it high, you might like it.
P.S. Add to your drama list! That way we know what you've watched and can recommend accordingly. If you're having trouble, I can help you out. It was confusing to me at first, how to add the dramas to the list, but it's actually pretty simple, if not time consuming. Anyway, hope you enjoy the dramas!
