This dorama gets a full 10/10 for its many merits (very interesting plot, beautiful message, great performances by the leads - Aoi Yu and Sakurai Sho - and by part of the supporting cast - most of all, Kazama Morio and Kinami Haruka - btw, too bad Morikawa Aoi's role is so small T__T) and despite its flaws (the naiveté of some details - active learning is indeed a great tool, but it's not so easy to implement it, particularly in a high school environment, as shown here; the ridiculously terrible performances given by Arakawa Yoshiyoshi - the guy can "play" only ONE character, and that's what he does *every single time* in *every single drama*...SO ANNOYING!!! - and by Takashima Masanobu - compared to him, even Dick Dastardly from "Wacky Races" was a credible, realistic and sober villain!!! >__<
