I'm completely obsessed with this drama! I know the drama is good when I binge-watch several episodes in one day!!!

This is the kind of drama I've been missing. It has old detective/investigation vibes in kdrama. The characters are all good at capturing our attention, and the plot thickens from the first episode you watch.

I really recommend this kdrama if you enjoy watching classic detective dramas. It's not a normal investigation, but trust me, it has that vibe. Kim Tae Ri and Oh Jung Se never disappoint, they are fantastic actors. This drama is not just about ghosts, jumpscares, no! It has a good lesson.

Update: I just finished watching this and highly suggest it to everyone. This kdrama is really well-balanced; it can be quite chilling, and then it can get extremely emotional. I burst into tears while watching the final episode because im so happy with the plot and the ending :') This kdrama is the best kdrama i have watched this year. Packed with emotions, lessons, and actions. Kim Tae Ri should be given a Daesang award for her outstanding performance in this drama. Not a single episode is dull.
