Some of the parts in this short story really did confused me, and I think the story needed more details.
It felt like I was thrown in and out between different timeframes if that makes any sense?
The only thing I think I understood, was that this blonde girl from the beginning, (who was Ishibashi-san's first love). was the same waitress in the ending, and her sudden outburst was because the love she felt for her, was not requited.. But it is only my point of view?!
Well like I said before, this story still needs more detail about the different characters, and it needs more substance instead of a rollercoaster, but other than that, I think it could've been a sweet story. :)
