what is the song that is being played? killer and healer

Which song do you mean? 

the one thats in the background

Can you specify it? You don't mean the intro or outro theme, right? Can you tell which scene/episode you mean? There are different background songs in this drama.

didnt realize there were so many. just never mind. forget it, thanks anyway

I'm not sure which one you're looking for but this one just popped up on my feed and it is gorgeous! ?
