Do you believe that a human soul can shatter like glass, scattering across the floor...
God says: The souls of those killed by evil spirits will never know peace.
God says: Everything in nature that cannot be explained has a corresponding second nature.
God says: Souls that die through malice will be trapped forever in the land of the dead...
That's more or less what this story is like.
This isn't that other Spirit Pact. Sorry, but they really have nothing to do with each other.
Ah! As for the couples in this story, officially, there's a master-and-servant pair who's also friends, an older-younger pair, a pair who can't stand each other, a pair whose truth won't be revealed until the very end, and more (there are just so many characters, haha... sob).
If you're patient, my dears, see if you can find them in the story, assuming the author keeps writing.
I saw you over there at Feilu, I didn't expect you were still here
