Its a real thriller. I like how they play those games sudden suspicion.. sudden thrill in the heart. Especially, Tao-chan she's so cute in this series too. I've watched every movie of her and it was only school life, shoujo, romances genres but suddenly seeing her in such a thrilling series is amazing... I want to thank the director Mr. YAMADA YUTAKA for composing such series and this is the first ever Japanese thriller series I've watched :)
