It was such a great watch. When I first heard about this drama I was doubtful because I usually get bored of dramas with plots similar to this one. However, I still gave it a try after listening to the OST, hearing about the positive reviews and high ratings and boy was I surprised! I ENJOYED it.

Things hooked me right away:
1. The relationships between the characters (even supporting roles)
2. Acting :D - Very talented actors/actresses
3. Soundtrack (The feels~~)
4. Story (the crime/thriller element was exciting! Haven't found a good crime drama in a while)
5. Surprises (you won't expect what's coming)

But, there are so many other reasons! I totally recommend it if you're into crime/mystery and love to watch a cute relationship between the characters! So many precious characters that I am missing right now T_T
