I have to say- the story will keep you at the edge of your seat the whole time. I am a big fan of City Hunter, therefore I gave this drama a chance because there is a lot of technology is involved. Definitely awesome!!!!! Too bad there wasn't any action, but who cares. The actors did an awesome job. There were well chosen- many cute guys (even those who are evil- so it's hard to tell until the writer wants you to know). As a fan of City Hunter, I loved the music- here it's pretty much the same story. SIMPLY AWESOME MUSIC!!!!! Therefore overall a great drama, if your into Crime and Investigation. You might be disappointed if your favorite genre is Romance. You won't walk away with nothing because there is a lot you can learn about the tech.
