This is really interesting. When I read this is about a gay guy's interaction with a fujoshi. I thought it was either going to be comedic and silly, or shallow and misguided.
What ensues is exposition about a closeted gay person anxiety, and its interaction with a society that rejects them, bridged through the lens of BL fandom (maybe, so far the fujoshi had only been an early plot device, but it may be more crucial later on).
This is different. This is probably the first time I see this kind of story told within Japanese society perspective, by a Japanese author.
