Beautiful World, Where Are You

the first half was difficult for me to get through, some of the chapter triggered me so much (even if I knew what the book was about, I chose to read it so... my bad)
the second half was interesting, I was just trying to understand the behaviors of Felix but didn't succeed lol
and then... the final chapter was kinda silly, I mean it was very simple and easy (but maybe we should see the life like Eileen did, idk)
