oooooo, interesting to see the genderswap coming to light this fast. I wonder if next chapter will have a hasty coverup (it's my cousin!) or something like that, or if the genderswap situation will be explained. Or, will she just say that she's a girl now?
Also, I dooooo really hope that she stays a girl... the manga is probably gonna be about her wondering whether she wants to live as a girl and trying out that versus being like a boy with Kyouko.
And the "I have no interest in boys" was peak, as was the ensuing promise of devotion. Lesbians and their promises...
