I'm relatively new to the j-drama scene, so this was one of the first series I've watched so far. What can I say? My experience absolutely wasnt a disappointment. I would've given a 10/10 rating but as every release this show has some flaws that would've been a dealbreaker for others.

STORY 10/10
The story itself got me excited and hooked with every episode. The way it handled pre-existing stereotypes (eg. "unpopular student who is new at school changing to a popular student") and re-eranged them to something completely new. That's creative storywriting for me. There never was a point where I felt that the plot was stagnating, from the very beginning to the last episode. Surely, the story is far from being realistic, but i dont really bother. It's fiction, after all.

ACTING/CAST 9/10 ................I'd actually split this into two parts.
CAST 10/10
I couldn't find any flaws to the cast. They fit perfectly into their environment and their appearances were distinctive enough even for an asian-face-blind silly european like me.
ACTING 8/10
2 points subtracted here, not for the acting itself, but for the way the series chose to convey it. The speeches were too long, not only for my taste but from what I've read, almost everyone feels this way. It's the biggest flaw, although it got better at the second half of the show. Other than that, there's nothing else I could criticize.

REWATCH VALUE 9/10
I'm sure I will get back to this show someday. This could take some while tho.

OVERALL 9.5/10
Maybe I'm giving away too many points for being too subjective. After all, this show will definitely not everyone's taste.
If you can endure long shonen anime like speeches, or even have a thing for those -I highly recommend this show!
Man, I really wish there was a second season or some kind...
