I started reading this right when the first episode of the anime aired because I generally tend to prefer manga over anime and thought the concept was pretty interesting, Having now watched the anime, or atleast the episodes that have aired (which have gone beyond the most recent manga chapter) I can now confirm what I felt was missing from the manga. You can tell while reading this manga that the story itself is actually pretty well put together, the side characters and even our loner mc have a ton of personality. The tone is light hearted and bubbly and the settings in which thecharacters get together feel a lot more auhthentic than what you normally see in highschool stories like this. The major reason for this is that this story actually considers the relationships its characters have outside of the main cast. It feels more like a living world and less like a setting for the drama of the main characters to commence. That being said the manga iteration of this story is missing a part of this charm. The art is fantastic but the subtle character moments that really makes the anime so endearing are lost in the transition from light novel to manga. They make the main character too much of an outcast in the manga, the chemistry between him and Yana isn't as fun, the other characters in the main cast also don't have the same chemistry as they do in the show, the weirdness of the president is turned up to eleven, you loose the subtleties and are left with the extreme character traits which does this type of story absolutely no favours. Granted I do not know how this is in the light novel, but seeing how the anime does it I am inclined to believe that the manga is the outlier.

Overall I would say that this manga is above average on its own, but inferior to the anime adaptation and likely also inferior to the light novel it was adapted from. Solid concept with a unique vibe though. Try it and form your own opinion.
