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.
