Chapter 1: I don't understand it. o.o First, your foreword really confused me - I thought Chanyeol was the one with hallucinations.(But I guess thats my fault entirely for being confused, lol). And then I don't really get the ending. Does Baek leave (like walk away) or die? Why would people hear "the hysterical crying of a young lad, and another desperately trying to comfort him" if he's dead or has left? I mean, then who is comforting Chanyeol? Or are they hearing the past before Baek leaves?
I like the idea of polaroids but I think it's so hasty. You left so many questions unanswered. It really developed quickly. o.o'
I think you have a beautiful idea though, I'll give you that. I was just left so confused so I didn't really get to enjoy the beauty that is the sadness of this story.

I'm sorry for such a long, y comment. ): Please, keep writing on aff! <3
