Amazing drama!! One of the best thriller mystery dramas I've seen.
The story line was awesome, I haven't watched the Japanese version or read the Manga so I can't compare. This drama always kept me in the edge of my seat, especially the last few episodes. I was low key hoping that they would kiss in the last episode.
The acting and cast is perfect. Kang Do young is really like a psychopath, his laugh/smiles always scares me. I love his acting so much, I hope he gets more lead roles in the future. The female lead is naive but not in a stupid way (like most female leads in kdramas). I love how she became more confident in the end. Cha Woo Jin was also super cool. I love how in the end he held Da Jung hand, a cute flash back from when they first met.
The music suited the situation/scenario. Most of the music was just instrumental.
Re watch value is definitely 10/10!! The ending is a cliff hanger, season 2 plss!!
