I only just found this story and I am sad I didn't find it before now, because it is gorgeous and wonderful and joyful and sad in all the best ways. The little bits and pieces and differences that you can find through the different loops are all so great, and the ending once you finally decide that it's perfect (enough) is great, too.
(I did end up going through an extra couple loops to get everything just so, and there are still questions I never found answers to, but I'm happy with the ending I finally settled on.)
