This drama is so good! I would heavily recommend if you don't get scared easily. The story is quite unsettling and disturbing, so if you get easily scared, don't watch it by yourself. As a person who normally watches rom-coms and school dramas, the difference between those dramas and this one is quite big. I would suggest to watch another drama to warm up to this one. For me, Tempted/The Great Seducer was a good bridge. Something to watch out for is that the whole story is just messed up. So, you might not feel scared and then you might suddenly get that freaked out feeling. Although it is definitely scary, I would say that it's not to the point of any nightmares.

Everything about this drama felt like a masterpiece. The story, acting/cast, music and rewatch value all deserved 10. But overall I would give it a 9 because a lot of the deleted scenes were so cute and important. This caused some characters to be underdeveloped. I also misunderstood some characters and got confused at some point in the story. I only got to fully appreciate the story and the characters after watching the deleted scenes.

bonus: the soundtrack was good
