A sorcerer has no future. Even the Satoru, the strongest sorcerer was trapped with heavy responsibilities. Just tomorrow, he'll fight the King of Curses Sukuna and there's nothing you can do about it.

You bury your face in his neck and drift off to sleep, but you don't dare. You're afraid you'll wake up empty and cold. He sees your worries and pulls you close, whispering into your ear softly

"Sleep, so that tomorrow you have the strength to cheer me up. Hm?"
