Brogana Sunfrog:
ah , I could recommend quite a few romance dramas but finding a romance with action in the right balance is tricky ! I mean you can't do much better than Healer ! but here are the dramas that I have on my shelf that have a good does of action along with some romance :
While you were sleeping
Lawless Lawyer [ heavy on the action with some scary dudes, but has romance with happy ending
Moorim School [a bit fluffy but a good bit of action with some romance & happy endings]
King Eternal Monarch [I'm not a fan of historical stuff or of the male lead BUT, this won me over on both counts, AND it is set primarily in the present
My Mighty Princess (movie) fluffy with action & happy ending
Man to man [ heavy on the bromance, but does have romance in it. I am not normally a fan of bromances but this one won me over.
Cafe Minamdang (Quirky & fun.has couples with happy endings but is more action)
I know the first three on the list and ı can say that they are good and Morrim school has a different place for me:)
King Eternal Monarch as you said ı am not a fan of lee min-ho but ı will take a look because of YOUR advice.
I will give a chance to the rest of them. Thank you soo much
