Apparently I don’t watch a lot of dramas that fit this genre because I was all gung-ho to answer, but could only come up with Arang and the Magistrate.
Wait, there’s also Surplus Princess (mermaids!).
I don’t know that I would list Padam, Padam as a favorite drama, but I adored Gooksoo.
You’d think I’d go with an awesome mother who was unfairly killed off, but instead I gotta go with Evil Demon Mom. Not that she was always evil. Or a demon. I mean, Eun Oh was willing to do anything to find his mother, which makes her kinda awesome. He only was willing to interact with the chatty Arang once he realized she was wearing his mother’s hairpin. How was he to know that his mother was actually evil incarnate and terrorizing her new son, Joo Wal? Being possessed by an evil spirit may not exactly be the best form of parenting, just sayin’.
But he does eventually free his mother from the evil spirit and then, for a few tender moments, gets to speak to her, his true mother, and she with him – until she dies. Yep. All that blood, sweat, and tears to defeat a powerful demon, and all for what? A few minutes with the person you’ve been desperately trying to find for most of your life?
