Masterpiece!! Top tier investigation, detective drama with peak thrilled, plot twist and unpredictable.. It was well written plot with never ever ending suspense that makes you on the edge of your seat till the end.. Love it!! The monologue that tells the story and mind definitely makes you more drawn into it.. The tone voice give chills in a good way..

Also love how they make duo between sharp, intelligent detective with criminology, profiling detective.. It definitely gives more credit to story especially profiling moments scene.. The thrilling is real!! Both Nakamura Anne and Yokoyama Yu really have good chemistry in drama ^_^

Overall the drama satisfying at its finest!! HIGHLY RECOMMENDED ^_^
