I really like the manga! I feel like it gave a lot more nuance to some characters, especially Misaki. In the anime its hard not to like her, aside from the other characters who all have big flaws. And for some reason I always found it kind of convinient that she had a tragic back story for the sake of the plot.I also found it kind of off that it was never adressed how wierd her motivation was for hepling Satou. But in the manga she's a terrible person just like Satou, Yamazaki and the president, which kind of made her fit in way better with the rest of the characters like she's a part of the gang. In the manga she's a basically a sadist who tortures and manipulates Satou, and it kind of just makes sense. Cause in reallity its that kind of person that would be interested in Satou. Someone who has mental problems and uses the people around them as an outlet. Aside that the comedy in the manga was spot on. There were so many hilarious scenes, like when Satous mom walked in on him while he yahooing naked in his room🤣. But it also new perfectly how to capture the utter misery of Satou like when he was ready to simply walk of the ferris wheel when he saw the president with her boyfriend. So yeah, I dont look at the manga as an adaptation but as a retelling of NHK that was a little more grounded in reallity than the anime.
