You first saw him walking out of a convenience store with a bag of popcorn and a soda. He looked out of the world with his four eyes, spiked up pinkish hair and red crimson eyes. But you decided to talk with him anyways.
You talked to him.
Like he was some normal person.
And that was enough to intrigue him.
And the second time you met him was in Shibuya, when he took over Megumi's body and completed his full form. Four arms, four eyes two faces, and an extra mouth on his stomach.
You asked him to bring back Megumi because you have something for him, but of course he refused. And now you're here in his hideout, tending his wounds and still asking for him to bring Megumi back.
"Just for a minute! I made these sweets myself." You said, wrapping a bandage around the wound on his abdomen. You know you shouldn't help him. He's an enemy, as Gojo said. He took Megumi. He killed thousands. But you don't know what took over you and decided to help him anyways.
Maybe it's the fact that there's an invisible string pulling you into him the moment you saw him at the convenience store. He didn't know why he was letting you help him even though you're an enemy who would possibly kill him. But all he knows is you're something to him. Someone. You're intriguing, interesting. He wanted to figure you out, he swears. That's all. But no, no it wasn't all.
He finally gave in, rolling his eyes. And for a moment, the tattoos all over his body disappeared. His once pinkish spiky hair became black like Megumi's, his body shifted into a smaller form—Megumi's form.
You immediately lunged in to hug him, but his body grew back to Sukuna's full form. He laughed as you immediately pulled away from him with a frown.
"You're the worst." You pouted. "I don't even know why I'm helping you."
"I didn't ask you to." He chuckled, his signature grin forming back.
