Guilty by Association

Finished watching 2 seasons (9+11eps) of Hana Yori Dango today! In case the title sounds vaguely familiar, it's the Japanese version of Taiwan series Meteor Garden (starring F4), which was in turn based off the manga series. Liked the comic when i read i back in poly but never watched Meteor Garden because i hated F4 back then. Was very undecided about picking up this series but the clincher was knowing that Erika Toda appears in the last 2 episodes of Season 2. So, loyal fool that i am, i started watching the whole drama from the beginning and suddenly i couldn't stop. Back that up with a cast of up and coming teen stars (Inoue Mao as Makino Tsukushi, Matsumoto Jun as Doumyouji Tsukasa, Oguri Shun as Hanazawa Rui, Matsuda Shota as Nishikado Soujiroh, Abe Tsuyoshi as Mimasaka Akira) and this is one of the better romance comedies i've seen this year.
Rich Kid/Poor Girl.
And of course one big advantage about watching HYD first is that i got used to Matsuda Shota's face, so i didn't have prejudices when i watched the first episode of Liar Game, which was much better than i dared hope for Erika's first lead role. She plays Kanzaki Nao, a much too honest and gullible girl (she went to the police to return a 100yen coin that she found on the ground; she fell for the same prank 42 times ..). Somehow or rather she get tangles up with the Liar Game(hosted by none other than Jigsaw(SAW) himself) and ends up getting swindled of 100million yen. Desperate, she enlists the help of swindler Akiyama Shinichi who is just released from prison and agrees to help her for half the share of the prize money (50million yen). Eagerly looking forward to Ep 2 airing next Saturday.
Toda Erika
Matsuda Shota
A very flustered Nao.
How did Jigsaw escape into this show?
