Honestly the story had me on the edge of my seat the whole way. The JP series is also tagged with yuri for what that's worth.
For those who must know: Yuuri does not turn back, but her gender identity is quite ambiguous even by the end. It's hard to call her either a guy or girl definitively. You know my side though. Yuri forever.
In the end they can't win against cock.IMO that's also true for most girls. They have such a strictly defined gender role compared to guys that most girls I'd ever met often doubt they count as girls -- especially if they begin to feel attraction to members of their own sex. I think one of the best ways to do something about that is with gender subversion. Be it yuri or TS friendships... or of course, TS yuri. BTW yuri shall conquer the earth.
