This drama is supposed to be based on a Japanese crime mystery novel that was made into a mini-series in Japan. I haven't the seen the original series but am a big fan of the crime/mystery genre. I'm also a fan of the two leads and went into this drama with anticipation. While the two leads had chemistry and you could tell the actors made an effort, they couldn't save the show from the terrible writing and 2D characterizations of the characters. The story-telling was a complete let down. The most annoying part of the drama was the voice over narration that over explained everything and didn't respect the viewer's intelligence. This was supposed to be a suspense mystery but instead there was too much corporate intrigue and domestic drama that felt tacked on to fill out the series to 12 episodes. The corporate intrigue was not engaging and a waste of the acting talent from the large cast. If you're a fan of crime dramas, give this a pass because there is no meat in the mystery. If you're a fan of the leads and want to see them in a romance, feel free to fast forward the other parts of this drama.
