This drama just has everything I liked. It had a beginning, a middle/climax point, and a good pace ending. Everything that was presented as a problem in this drama was answered and solved. There were no plot holes for me as everything connected to one another. Even the mini stories of the ghosts had a beginning and ending. I like this because a lot of times when dramas goes to this format, they can leave some mini stories on a cliffhanger but this drama didn't do that and I give kudos to the writers for the detailed writing and scenes. Even the last episode flowed so well that it didn't felt rushed and it was a satisfying ending.

Now there's no romance though, despite me seeing the connection and chemistry between our leads. I did wish for at least some scenes for this but at the same time I was okay with it as well because the story was the main focus for this drama.

Music wise, the osts were good but not one I would add to my playlist. I kind of wished multiple osts were played often in this drama. Instead, I think I heard more of the same song in each episode.

Overall, this drama is definitely one of my favorites for 2021 just because the plot was well written, ending was well pace and not rushed, and the scenes and visuals looked very cool. Everything was well thought out.
