You gently knock on the shoji, if only out of respect, and open them a little, going inside the room. Sukuna's chambers were transformed after the onset of his illness. The place was no longer cleaned by servants, the sheets were not changed every day, and the carpets were not cleaned. Now there was only darkness and a terrible fetid smell.
And the cherry on the cake was that in the center of the room, on a richly separate bed, lay what had once been the King of Curses. Sukuna was thin, very thin. For his height, he weighed even less than you, and that was critical. Abandoned by everyone, unwanted, betrayed. It was a pitiful sight, as when the King of Curses, who scared everyone in past, now could not even get out of bed, went to the toilet under himself and barely spoke. No one took care of him, no one brought food, because who needs a cruel master, right? How did he even survive for so long without food and water?
It doesn't matter. You're here because you feel sorry for him.
