This is the kind of drama that is going to be hard ro review for me. The reason for that is this show had very very good moments but at the same time alot of stuff were a little bit dragged out and unrelated to the actual storyline. But let me tell you what the best part of this drama is, it's the character Shizuka played by Kaho. I might have to think about it abit deeper, but just at the top of my head she is one of the most interesting and mysterious characters I've seen in a good long while. Even after finishing this show I want to know more about her. So, the storyline is pretty interesting at it's core but some moments are dragged out. I don't mind sitting through slow dramas as long as the good parts are good enough and I felt that about this show. The good parts were worth the wait. If you can't stand slow dramas you might want to avoid this or at least expect to not like it as much as I did. The acting is pretty much flawless, that's what I've come to expect from WOWOW shows at this point. Kaho, like I said, is amazing as Shizuka and the various police officers, private investigators and other supporting roles are great. I have to admit, in the first episode I kinda felt Kaho was miscast as the main character but it changed the second she appeared in the second. The music was very good and I still remember the "main score" of the show which I really liked. Ultimately the reasons I can't rate this show higher are these. The first episode is really slow until you get into to the actual plot. Also I didn't really love the ending, I won't go into that cause of spoilers. And last, I wanted to know more about Shizuka. But I recommend this drama, IF you think you can manage the slow pace.
