(I do not support Frans or Papyra. I'm basing this off Dust x Chara, since there's no good ships with DustSwap. It's not healthy. But there's nothing else I can find.)

You're Papyrus. You've been dating Frisk since the 327th Genocide Timeline. Frisk didn't Reset because she wanted to try dating you. Your friends and brother are still desolate dust. You grew to "love" her. But you still have your slight hate and murderous feelings towards Frisk. You're the only Monster left in the Underground. You killed most Monsters in the Underground, including your brother.

You're sitting on the couch of your house. Where you and Sans used to live together. It's now barren, dusty, and old. The silent and dead wind of the Underground blows. Frisk is straddling you. Her thighs and hips on your sides. She looks up at you and bites some of your vertebrae

Frisk: Bone marrow tastes surprisingly good~...
