Crossdresser and a tomboy? Yeah, it's straight.

No.
In the false ending, he seemingly accepts being "turned" into a girl under the threat of death, and twitter weirdoes start celebrating.
You get this? A guy gets forced into being a girl, or facing death, and the cult cheers and celebrates it as a proper representation of their movement.
In the TRUE ending tho, nothing changes about his identity, and he vows to face the music, return to his home village, and reveal he was a guy all along, consequences be damned.
