I kind understand your point but I’m 17 and if a was reincarnated i would act the way she act to because it a different world that would make me excited and sometime I would think to myself that i want to earn a-lot of money then just do nothing and stay at home your go out and not to do any work but that not how life goes ╮( ̄▽ ̄)╭
Honestly tho. I can so relate to her. You spend basically your whole life studying for exam after exam with only more exams in sight. If I was transported like her I would laze around and want my life to be as easy as possible. I don't quite get what you're trying to say but yeah of course nothing is free and you obviously have to work for it but when you study and you haven't seen the rewards for it aka graduating or getting a good job cause she was only 17. You won't wanna work anymore so its only obvious that she doesn't feel like studying.
She really is a 17 year old girl who dont want to study... I cant call her mature yet with this kind of mindset like girl if you have given an opportunity take it nothing in this world was free you have to work hard to get what you want and you being a brilliant girl was a bonus but it was on your attitude to strive hard and work for it ...
This is a story where fantasy really is good to your brain escaping from reality....
