the most popular answer will be her official gender but right now, i can't decide so it's ambiguous and up to your interpretation. (i will use she/her pronouns because she presents as a woman)

so "l" morgado is a portuguese person living in brazil. her name at birth is masculine but since she's presenting as a woman, just goes by L to leave her real name ambiguous.

though femininity does not equal womanhood, l does typically feminine things like wearing skirts/dresses formally and painting her nails, which appears to give her euphoria.

every time she has to act as a character in a play or something, she always chooses the women characters.

she also keeps the fact that she was born male a secret and doesn't tell people so she can live as a woman.

i'm leaving it ambiguous but i would read her as a trans woman.
