The first few episodes were a bit boring for me... but starting at episode 5... it became intense and I found myself concentrating watching it and looking forward to new eps every week.
Story wise... its a different kind of plot and there's some twist there.
I though the twin sister was dead at first.. then the plot twist.. episode preview gave away the twin's fate. Since then I knew the twin was gonna stay alive.
But the background story of the killer was a little unexpected for me. They created a great plot for the killer. Tho would love to know the ending fate of the killer after he got caught and the 2 robbers.
I love how they made it a happy ending for the main couple and showed some romance towards the end. If there's none, I figure it would be a little boring.
Casts was excellent... they played each characters well. Moon Geun Young (MGY) portrayed both characters well.. Not many actress can pull "autistic" character well. But she nailed it. and Iove her main character as a detective.
Kim Sun Ho... I love his acting.. he's been great since "strongest deliveryman"... love his deep voice and his dimples... he portrayed the character very well...
The rest of the actors & actresses were also great...
Overall.. this drama is great.. love watching it.. will surely re-watch it after a while...
If you are looking for a light drama.. this is the one... just sit back and enjoy the drama..
