"Oh Zoe, Zoe Bosch, I've got a crush on you, girl," she sings. "'Cos you are amazing, drive me crazy, oh yes you do, oh yes you do.
"You're so special, baby, you are special.
"You're funny and you're daring, you're loving and you're caring for everyone around you.
"And I love you, oh, I love you."

Katherine has never spoken publicly about her sexuality, but she has spoken about how happy her school life was.
"My high school experience was a lot happier than Hannah Baker's," she told the LA Times.
"I went to a gifted and talented school, so I was surrounded by really interesting people from all different walks of life and I had a really strong friend group.
"The school was very liberal in that I had freedom. During my study periods I wasn't being watched by a teacher so I would go to the auditorium and write songs.
"That's maybe one of the reasons why I was able to become an actor, because I was given the freedom to do that."
