Ive read both the novel and manga, and watched the anime. I honestly believe the manga was the best. Effective in expressive emotions, characters were well developed, captured moments of drama and comedy very well. The novel gave the extra detail about the Satou-Yamazaki-Misaki relationship and characters. THe novel is also alot more disturbing- while there was only two drug scenes in the manga, the entire novel was littered in drug refernces. The novel also had various serious suicide attempts and violence.>>12808811
Mirrors my feelings exactly. I was pissed off at having a shitty ending for W2TNHK. It seemed absurd that Satou would suddenly find motivation, after all those previous chances, in the manga and anime. The novel had Satou ending on the same note as the beginning, i.e he was alone again, and that made me RAGE even more. But reading your post, II considered, and I can't really put a better way to end the series. I guess its the way it is.
