This could have been way better if it had been a long running series and completed with the manga ending not that i have read the manga yet. The 41 episodes cover less than a 1/3rd of the manga. Because of this the show feels like a prologue to a very good story. Compared to touch (another work of the manga) h2 feels a bit more mature as the characters have better traits to them. The characters of h2 are witty, strong willed and don't get pushed around whereas the characters of touch were wishy-washy, casual and undignified. The romance in touch was frustrating to saythe least. The romance in h2 is at the starting point in terms of drama, for more the manga has to be read.
The atmosphere in h2 is good and the show is enjoyable with good pacing. The comedy scenes especially of one of the characters is hilarious.
Honestly this should not have ended abruptly whatever the reason may have been.
