The protagonist acts like how an introvert thinks extroverts (or weirdo-normie) would behave and not like how real people act. The loud and obnoxious characters combine with their self-consciousness make this chapter really hard to read. The art is nice though.
Am I missing something or the reason why she has bad grades is kind of omitted as she is interested in magic and did try her best at studying? If so then the whole premise is pretty weak imo.
At this point I feel like the normal goody two shoes hero is even more tolerable than the trashy subvert-your-expectation hero trend in these isekai mangas.
