   Summary

   Ah yes. The classic ‘’Heather’ convinces the skeletons you’re an evil human so now it’s a EVIL reverse harem’. Right?

   Oh? But what’s this? A TWIST?

   Sans couldn’t live with himself after what happened to you, going near insane after you’re gone. So behind the others back he uses the machine to undo what he did, except it didn’t. He can still feel his sins crawling on his back.

   Oh well, it’ll all be worth it once he has you back in his cold hands again. Screw the other skeletons.
