Looking for a story

I'm looking for a story and this is basically what I remember of it:

There's an uncompleted story on BC that really caught my eye. I remember that the main character's name was K.T./Katie(K.T was the characters initials as a boy and was trans) when the family moved his boy clothes got lost and he was allowed to explore himself. Ends up befriending the neighbor who has a friend who is trans. She has another one who was Lesbian and it's set in San Fransisco
