"Would you sacrifice me to save the world, or sacrifice the world to save me?" you jokingly asked.

"I'd let the world burn for you, darling."

And that lighthearted discussion was just yesterday. However, he was speaking with sincerity.

Standing behind him, you had shock and dread in your wide-open eyes. As he had warned the night before, there was a flaming world in front of you. People's cries of anguish could be heard as they ran around, their bodies melting and burning. The sky was red, the trees were burning, and all the buildings were collapsing. The smell of fire filled your nose, then Sukuna finally turned his attention to you.

"I told you, I'd let the world burn for you." He grins wickedly.
