Recommend old Kdramas

I recently watched Oh My Ghost, I loved it, it's not that old but I loved it, and now I'm looking for an older drama so I can get it out of my mind, it's one of those dramas that makes you feel empty when you finish them. So I want something just as good to fill that void, thanks to everyone
