Once upon a time I envisioned OP ending with the roommates moving out to go their separate ways. I had a twisted epilogue in mind, in a salt-the-earth fashion, where Eve and Hanna run into each other many years later, and gradually morph back into their tiny child selves as they catch up on life. In the end it just felt too bleak, too nostalgic, and it just wasn't how I felt anymore. 2017 was the best year of my life. 2020 is the best year of my life. The girls have a shared past, but against all odds, it doesn't define them. There is no symbolic continuity from their preschool days - they've both changed for the better. In short, I wanted OP to end in the present moment: no tearful goodbyes, just an inventorying of what brought them here. Eve and Hanna are best friends, who are also implicitly growing apart because they don't need each other like they used to. It's not the end; it's just the new shape of things.
