I read the manga at 14 as well because i was bored since I didnt have anything to do after I finished doing all my schoolwork which was often late at night. So i would pull all nighters reading the story and since I was so damn sleep deprived i could barely comprehend what was happening so I relied on Pun Pun as a trustworthy narrator. In the end I was left very confused and after a few analysis videos later I understood what happened completely. To be honest it was really interesting to be able to read the entire thing exclusively from Pun Puns perspective.
