Heather Coven

Heather Coven is Ky(lie)'s older sister. She initially resented and misgendered Kylie due to her seemingly "not wanting" the femininity that Heather envies, though she later comes around and supports Ky. She lives with her sibling and is is in university for most of the story.

Sexuality

Heather has had a few boyfriends in the past, and has kissed Fara once when they were both drunk. According to Ky, Heather claims that she has no interest in anyone, but is attracted to everyone when drunk. She later states that likes things simple and isn't thinking about marriage or a committed relationship. In the epilogue, she is revealed to be dating Kellen.

Gender

Heather has Complete Androgen Insensitivity Syndrome (CAIS), hence she doesn't have a period and can't have children of her own. She identifies as female — the gender she was assigned at birth — which makes her cisgender. (Although some would call her Ipsogender, which is a way of saying an intersex person agrees with the sex they were assigned at birth).
