If I were the library,I would select a genius person rather than mc!!I mean I dont have any gain from selecting an ordinary person! I am sure if I checked clearly i could find a genius person with passion! It would be nice if you mentioned a sort of backstory or plot about mc or the library that made them choose him!
...The window of a door may break if you stumble into it but, a glass door? Those things are thick and harder to break even if you kick them, what kind of cheap library puts weak glass doors? No matter if they are public or private facilities, the owner should get a warning from the related security institution of their country.
