Kristen and Penny have been best friends for 10 years, And just before Lily was born, she might have well been living with Penny despite keeping a nice apartment in Melbourne. They became official flatmates before Lily was a year old. Kristen has been trying to balance a work and home-life while trying to get her books published. Penny has tried to be as supportive as she could be, even making sure that Kristen had a nice home office. And although Lily is in no way her actual kid, Kristen did help raise her, and has been called mum since Lily was four, so theres that fun family dynamic of two moms who are in no way romantically involved, or married, but they basically are, and she's not deaf to the rumors around town.
I do have some plot ideas, among them possibly exploring some sort of budding romance between Penny and Kristen. Which, super confusing for Penny cause she really doesn't feel attraction for anyone, but perhaps she can, and thats okay? Kristen has always been far more open, and very accepting of peoples boundaries, and she's just happy that she can spend time with her best friend and her adorable daughter. Just, one odd, happy family.
