Main CP: Sukuna and Yuji, with a little Yuji and Sukuna too. (Honestly, I just want to... torment the King.)
During their final battle, Itadori Yuji said something, and it truly became a curse.
Then the two of them returned to the beginning of the story with their memories intact.
This story was inspired by a classmate's idea: "Going back a few years with your memories."
Meaning: If they got another chance, could they change the story's ending?
