Can someone explain the couple's genders and sexualities again?
Teresa is biologically a woman (sex), identifies as a man (gender) and likes women (heterosexual).
Franco is biologically a man (sex), identifies as a woman (gender) and likes men (heterosexual).
So, they're both heterosexual (Biological sexes be damned! ?️?) and they fell in love without too much manga-weirdness.
The translations of the vows had me confused, since they use the pronouns belonging to the other's biological sex in there, so I was wondering if I missed something.
