This is the very first Jdrama that I saw. It has got a very intriguing plot. The initial episodes focused heavily on bullying and it was a lot of fun to watch that. But to think that such a thing could exist in reality also gave me goosebumps. I expected F4 to be less evil as the story progressed and in fact- they turned out to be very nice guys. Makino Tsukushi is a very tough girl. Apart from that, the cast was good. They are all good actors. The direction of the show was pretty good and the writing seems to be excellent. It is a no-nonsense show except for the T.O.J. plot which was so boring and that is the only place where the show felt dragged. At least I can say that it is much better than Boys Before Flowers (Korean version) even though there is zero glamour in this version. Overall, it is a good show with a good rewatch value. I haven't yet seen the second part but I might give it a try in the future.
