@Plykiya yeah thats the point though, the MC of Hourou Musukou is actually trans, hence its rude to call it crossdressing because saying a transgirl who wears girl clothes is "crossdressing" implies you believe the transgirl is not actually a girl. im not sure about the FtM character of the story, that part got confusing at the end, but the MC was clearly written as trans
sometimes however a transperson may call it crossdressing early on, but this is because they themselves dont yet see themselves as a girl or boy, im trans myself, i know this from experience, but that still doesnt change the fact that its not actually crossdressing as a transgirl is a girl, not a boy dressing as a girl.
