you know when you start something bad and know it'll end up bad but have to finish it just so you have some closure? well, this is the drama for you. i figured this being yamada yu drama, i would enjoy it (as she's great with comedy) but dramatic roles, not so much. story: the story started off very well but got extremely formulaic. you could actually watch the first ep and skip to 7, then the end if you didn't want to sit through 12 episodes. the writers had a pretty interesting concept but that concept fizzled with the crappy thursday mystery formula (bad guy of the week) and i think they couldn't piece together a decent story while incorporating that element. i think if certain points of rena's childhood were fleshed out a bit in this drama, there would have been a bit more depth to her character than scared woman. it was actually irritating that none of these characters had much of a backstory and the one character that needed flashbacks, didn't get it. that made it hard to sympathize with with the cast. cast: eh, you go to war with the weapons you got and that's what the cast did. over all the cast did an ok job but the one character that stuck out was the detective that worked with kazama. the rest of the cast was pretty forgettable, including yamada yuu (really sad) music: the soundtrack was actually great. this is one of the few mystery shows that didn't have a cheesy opening/closing song and it's a shame it was wasted here. overall: do you have 6 hours to waste? yes? jump on in. recommendation" if you want to see yamada yuu in a better drama that showcases more of her acting skills, i'd recommend seigi no mikata or gakeppuchi no eri.
