I refer to "Story A" here quite often. It is my shorthand for a typical story that encapsulates the standard tropes of what we now think of as a "Yuri" story.
This weekend for my column on Hooded Utilitarian, I trace the history of "Story A" and walk it from the past through to current iterations, in 40 Years of the Same Damn Story, Pt. 1.
Next month I'll be looking into the origins and iterations of another very typical Yuri trope.
Enjoy!
