not romantic not platonic but a secret third thing [what would happen between earth and the moon if the earth stopped spinning as illustrated by xkcd randall munroe]
I’m remembering that they say the moon is so big because a rogue planet crashed into proto-Earth and broke off a chunk, which clumped together and started orbiting the rest.
I’m remembering the concept of soulmates, who used to be one soul, but were torn apart by heavenly forces.
