Cosmin doesn't want to be a girl. He just enjoys once in a while wearing this kind of stuff. If he wanted to be a girl he could have trimmed that beard fluff. Just being a sissy boy here and such.

Its super comfy to wear even if it bums Aurel a little, I think he actually wears a more simplified get up under his regular work clothes , so that once in a while, during a report filling or before a businemessman bursts on his office for a meeting, he kinda disables the security camera, unbuttons his shirt and pants, undresses a bit and does a dance in front of the mirror. Althrough he kinda does a sound that on an onomotopeia would be connoted as "~♥" and does a little shoulder jig during meetings to mess with the silky straps as well, but its more of a little rush to go through the day.

Hey if Aurel can undercharge customers he likes being with Cosmin can have his ways as well too, specially if he can hide it well from assholes and such.
