I was in my jhs year when I first read this book. at that moment, I didn't really understand yet. I mean, it was just a conversation between a dying girl and an angel, no? but now I re-reading it again... still didn't know much hahaha, need so much focus to finally understand what the author wanna bring to this book, but maybe it's just because I read the Indo translation one. it was a good book, tho. u just need an extra focus to finish and understanding the book.
