This series is like the spiritual successor to Honey & Clover, which is just about the highest praise I can give to a slice-of-life anime.
(Not to mention that the main character's brother has a scene at Japan's northern-most point on a motorcycle, hnnng)
While I strongly feel that this series should be at least 36 episodes (I wouldn't even mind 50), there is enough development for at least the main character in the limited time. However the supporting cast is rather static as a result, whereas H&C had the time to development almost everyone. Both series have a superb balance between hilarious antics and serious moments.
Recommended for anyone who still feels like they have growing up to do.
(It's been a while since I've watched an anime eh)
