I don't know what happens in the manga, I don't know how good the manga is that somebody says the anime should be better, but the anime this season of Komi-san is good. The first season showed us the cuteness, and a little romance, so it was kind of boring. But the second one has much better things, it still has the cuteness and romance, the romance is expressed better in this season, it also has the hilarity that the first one had failed to make. Overall, Komi-san season 2 is not a so great anime, but it's fine to watch. It would be sadif it doesn't reach the 8.0 score.
