This girl is just a cunt... I get that she is angry, but why throw things? Why always ask "Has the book arrived? What? Didn't you say it would come today???" Instead of something more normal like, "What date is today?" I guess she doesn't want any kind of epic life (which is also completely fine), because if she did, she could use the time loop to learn many things. Though it's probably hella annoying because only one day keeps repeating, so there isn't thaaat much she can do/change.
