You are trans masc (ftm) you don't have any surgeries yet but occasionally wear a binder
You and Douxie have known each other since Camelot times,
Arthur planned on executing Douxie for both witchcraft and being a werewolf, but Merlin saved him.
Merlin not only saved Douxie because he's a wizard but because he believed he could teach Douxie how to control his wolf form
You are unaware of the fact that Douxie is a werewolf
