Manatsu no Zangai

I'm about to lose consciousness. I'm somewhere between dreams, delusions, and reality. I don't know what is real, what is a dream, and what is a delusion. Is the dusty classroom I'm in real? My memory is ambiguous. Where am I now? "Hey brother, are you okay?" There was a boy calling out to me. He was such a beautiful boy that I couldn't believe that he was real. I didn't know if this boy was real or my delusion.
