I would comment on how the new character hating the MCs transformed state us a new spin on things, but it really just reinforces the feeling of this being a transmasc story. The whole bra picking scene didn't help either, given how vastly different in tone it was from a normal TG story. There was a certain degree of disdain completely unrelated to the normal feelings of taboo and fear most TG protagonists show, nor was their any hesitation to enter the store itself. Exactly how I'd imagine a guy raised as a girl would react to having to purchase a bra.
