Okay! So I finished this drama just like 30 minutes ago in four days so it's fresh in my mind. The story is great, it's original, it's neat, and the suspense made it hard for me to not press the next episode. Although there were a few scenes that I skipped because I got bored. (mainly car scenes because they lasted too long but it wasn't too severe) The acting and cast were amazing. Honestly, the acting is good. If you're scared too watch this drama because you might think there are bad actors, just watch it. The acting is amazing. And the characters were just perfect. Music, I gave it a lower mark because there was never an ost that stuck in my mind. The first few episodes may have you bored, but just keep watching it, because you'll probably get hooked after 5 episodes. Idk, a lot of people say it's pretty similar to qihm but I didn't find it similar. It's more of melodrama but, there are the happy moments that will make you smile and laugh because it's too cute. WATCH IT.
