    CoolBeans Says:

    This starts out as a good detective drama with the look and feel of Gap Dong, where the strained small town police struggles to keep up with the very smart serial killer. It grows slowly to become a Great drama close to the level of Signal where a detective from the past helps the youngsters in the future. Jin Hyuk is more than eye candy in this one. His reactions when he sees new technology like smart phones are believable.

    Macchiato Says:

    Very exciting and engaging. Really looking forward to each new episode.

    Hannah Says:

    I’m excited that I knew it all along that Jae Yi is Kwang Ho’s daughter. I kinda ship Jae Yi and Sun Jae together. I bet Kwang Ho’s gonna approve Sun Jae as his future son-in-law if he goes back to the past.

    ica Says:
