Yes it's the same concept as Gokusen, but its way better. Its edgier, its funnier and its got Mokomichi! I really liked this drama because of the exciting plot and situations that unfolded. I also liked how it had a touch of a psychological aspect to it as Otowa (Mokomichi's character) really scammed everyone by getting in their heads. Although the main concept is that this teacher comes in and changes the students and the school by teaching in unconventional ways, this story has so much more. The teacher isn't a teacher but an ex conman on the run, and we don't really know his name. I liked how this drama really let its characters mature and even though the viewer is privy to the inner workings of the con-mans set up you still don't know how things are going to turn out. This isn't a tear jerker but makes you think, laugh and gasp.
