I tried to like this unfortunately I fast-forwarded most of the episodes, especially after 11 or so.

I watched this because of IU and she did not disappoint. Her visuals plus the visuals of the drama itself is 200%. Her outfit changes were GREAT. Her acting is superb too with a lot of cold yet funny lines and moments. Part of the bg music makes it even funnier. However her chemistry with the ML was lacking.

The side characters were likeable, but not great. I did like their backstories. Mago is probably my favourite.

The ghosts had meh stories and endings. I sometimes expected more but each episode fell rather flat with how the ghosts were handled.

the FL's main story was good, but took too long to be explained. There was a huge gap in the middle where they were focusing on the side characters.

Overall, a 7/10 for me simply because of the stunning visuals.
