i wonder if you have any thoughts about how marcille always seems to dislike it when falin wears men's clothing ( i bet she wears it out of its comfiness rather than because she prefers masc style tho, although i hope both lolol) and super short hairstyle

I wonder if it's just her interest in cute feminine fashion in general or maybe there's something more

For the clothes, at least, it's like... Marcille is probably more horrified by the clothing being actually made for and marketed to men than anything else. I bet she'd be fine if Falin wore the exact same things but they were in the women's section, or at least, branded unisex. She would be so so silly about arbitrary stuff like that in a modern setting.

The hair I think is a tangled issue of Falin's resemblance to Laios getting a little too obvious for Marcille's mental health, and Marcille's own very intense relationship with how (female) mages should treat their hair. Also, since it's mostly a joke doodle, I kind of took it as a flanderized Bad Taste Marcille being horrified by a woman with short hair because she buys into gender norms. Some people are... weird about what women do with their hair and unfortunately I can fully see how Marcille can be weird like that in a vacuum joke setting.

(there's also something to be said about how this kind of femininity policing could also be used as plausibly deniable homoerotic subtext. like, girl, why do you care that much about how cute another girl looks? hm?)
