"Insurance was the last love letter." ..is one thing that I've learned and reflect from watching this drama. This is hauntingly beautiful story that brings you to a world of dark mystery of a young woman Egi Touko. There aren't that many mystery or suspense dramas in Japan. Usually, you'll get an episodic drama with a "detective-genius-who-solve-all-case" so when a good one like this, it should deserve a good rating. Well, just because the genre is mystery doesn't mean it's always an episodic. Sometimes, it was to confuse and leaves to audience to think for themselves about the events regarding of what the conclusions will be. The script was very well-written that gives a chilling feel and yet captivating. The actors did pretty well in portrayal especially Matsushima Nanako. She has this cold and creepy aura in this one that her acting transitions made me "never-to-be-forgotten" of her. Eiki and Touko has a very good chemistry, well.. this is not just an eye candy drama though. Now, in this drama.. YOU are the Detective! :) I advise you to just go with flow in it or else, you may lose concentration to the story. Do not "overthink". :DD I recommend you to watch this drama, nothing to lose if you try.. Who knows? You'll never know that you're missing. :) ENJOY! ^_____^
