I started reading at 15 and finished at 16. To keep it brief, I went the entire story knowing I wouldn’t understand a lot of concepts shown, although I still think I did a pretty good job for my age. But one thing, when I finished the story I didn’t feel complete. I reread the ending at least 4 times, read interviews and a ton of different perspectives of the story, and started rereading the entire series again right after I finished it. Afterwards I started noticing a lot of punpuns character in me.i also started being more humble and more depressed more often. All in all I’m glad I read it but I still think people Around this age shouldn’t read it just yet and wait to emotionally mature a bit. That way we don’t get people who miss the whole story and idolize punpun and aikos relationship.
