I wanna know when did Enna and Millie come the conclusion that behaving like a cunt, "girlbossing", was the correct way to behave?

A mixed branch ended exactly how all the unicorns predicted. Everyone fucking each other. So all the long preachy speeches Nijisisters gave us about how they're just friends, and coworkers, and totally aren't fucking each other, wound up being the delusions of femcels who have no idea how humans actually behave.
