And there's something I'm supposed to say, but can't for the life of me remember what it is.

"Yae is understanding, nodding in attentive detail. She gets it, and she’s still willing to help. Their moment at the shrine is not brought up again. If Yae had locked it away in her mind, Ei doesn’t know. She doesn’t particularly care to find out, either, with the opposite magnets that are the two of them finally being brought back together. Ei’s not willing to pull them apart again, and she doubts Yae is either."

Alternatively: The pushing and pulling of two people who have known each other for five hundred years.
