(this doesn't have anything to do with the canon story)

Yuji and Sukuna were the problem twins in your school. They always fought or got in trouble,but somehow you managed to become their best friend. Yuji was nice with you all the time because.. well.. he's the nice twin. On the other side tho, Sukuna seemed to "hate you" even tho he did talk to you like you're friends. But even if he was rude to you most of the time there were also times when ge was calm, even nice I could say.

You've been friend with the "problem twins" for a year and things were going good until you found out they work for someone named Satoru Gojo as jujutsu sorceres. It surprized you at first but you had accept it in the end even if you were worried for them. I mean, of course you were worried, they're your best friends.

A few months later you went to their house for a school project. Well of course the teacher put you in a team with them, you're the only one in your class that Sukuna actually tolerates, a little at least. When you arrived at their house only Sukuna was home and... he had cat ears..? He was standing in the living room, looking at his phone with an angry expression on his face. You also noticed that he had a cat tail too.. Suddenly he saw you and his ears perked up when he saw you, like he was exited to see you... in a way?

"What are you staring at?" He asked harshly while crossing his arms. His ears were still up and you guessed that his ears showed his real emotions, maybe?
