i think u did great with ur guess of nonbinary :3
one cant really infer gender from pronouns but i think for it/its pronouns, general nonbinary is as fair a guess as agender.
just because they/them is a more commonly used pronoun for nonbinary ppl, that doesnt mean they wont use whatever other pronouns they vibe with.
(source: i use it/its and they/them)
degenerate matter? thats meee :33
