After 80 chapters, nothing noteworthy has happened. The worst part is the lazy setting and lack of time flow. There are multiple classes each day, yet everything we are shown is as if there hadn't been any classes in between (even though days do pass).
Then there's the characters; everyone has nothing else to think about other than the MC, and everything that happens is a rip-off from other series: character traits, scenes, setting, etc.
With so much going on, the author oversimplifies everything. Introductions come in two forms:
Oh, there comes the (stereotype nobel) whiny prince. I should be careful not to mess up with him since I've never known him, nor is he my roommate. We have no reason to interact. So BFFs (or enemies) from that scene on.
The other version introduces a stereotypical fantasy race (dark elf, dwarf, half-demon, etc.) and gives them the backstory from another series.
And the worst of all characters is the MC. If you dislike random characters being called geniuses, you're going to be appalled by this series. The MC is the most inconsistent character ever. The story starts with his reincarnation after his graduation, explaining how he wants to live a peaceful life and how he has to work hard again to achieve that. Well, screw that. In the rest of the story, he's sort of the mean magical version of Sakamoto; he's joined a cult and wants to join at least two more; he has made enemies in each class; all teachers are obsessed with him; he has already defeated a top-tier antimage assassin (destroying any possible powerscale that may come after). And all this while badmouthing most of the characters, but rich in his thoughts like a good Korean MC.
I mean, most of the story is self-contradictory. One of the main points is how his massive mana pool should make it hard for him to learn or do basic stuff, but since that's only a rip-off trait, they just remember that when it's convenient...
