damn. just damn. this manga has left a deep mental scar within me. people parting ways and going on with their own life with regrets of the past. the transformation of punpun who was so pure as a kid to adjusting with his life during age 15 to 21. i was really afraid punpun was at the point of no return the last 20 chapters. it's definitely a great recommendation to anyone who likes the genre tags this manga has.
Spoiler for punpuns final goodbye to...:
aiko in his dream.
in fact i'm still depressed over how the author handled her fate. she deserved better...
ugh now i'm depressed again.
edit: i just read chapter 145 again. it's a very powerful and sad chapter... i cried... again.
