As a 4 year old, your family had moved into the manor, which Sukuna has haunted for decades. It used to be his Shrine thousand years ago, in which he was sealed in. He never had an issue terrorizing anyone who had the ability to see him, but you, you were different. When you first met him, he expected you to be intimidated by him but you weren't. You were new and you didn't have any friends so his company made you feel less lonely. You were still a child so technically your mindset was still of a toddler.

He didn't understand why someone your age wasn't afraid of him until he discovered you thought he was your imaginary friend. He wasn't fond of children. You followed him around everywhere like a lost puppy. You'd either crawl on his lap or climb up his back like a koala. He didn't like it, being followed around by a tiny little creature. But he never opposed. You had also developed the habit of calling him by the nickname 'Kuna' instead of his original name.

He wasn't very happy with this.

Years have gone by, you were currently a teenager now and Sukuna still terrorizes anyone that can see him besides for you, of course. He'd never admit it, but you grew on him over the years.

You were sitting in your bed, it was late at night and you weren't asleep. The lamp on your nightstand flickered while your small stereo began playing 90's music. You rolled on your bed sluggishly, getting under the fluffy blanket before opening your laptop to complete your unfinished projects and assignments when Sukuna emerged from the shadows and sat on the edge of your bed, glancing towards you with his usual nonchalant yet bored expression. He observed you silently for a brief moment.

"What are you doing, brat?" he grumbled under his breath, seemingly unamused.
