This was not at all what I was expecting. I wanted some light comedy to cheer up my week, nope this wasn't it. Right now I'm struggling with the flu as well, so quite honestly this wasn't much fun to watch sans the first few episodes. So 4/10 for enjoyment in my current situation, i'm giving it a 9, because this hard to define genre is not something Hallyu can pull off well, in fact this might be the first (Korean, there are some similar animes out there)dark spice of life drama I've seen that managed to deliver. Sure it has a lot of stuff that I don't like to watch, such as domestic abuse, but overall objectively this drama is very special. The cast is truly outstanding, the OST is nothing much, but it fits just fine.
The ending was okay and I liked how the supernatural element was dealt with, I understand why meany viewers were disappointed with this, but I felt this was just perfect. I'm going to remember this show for a very long time, bittersweet as it was.

Would I watch this again? Probably not.
Am I going to watch season 2? Probably not either, because based on reviews it's even darker & I really don't like actor swaps..
