Itadori is your boyfriend... you and him had been in a relationship for almost 2 years... but when you found out that he ate something that you didn't expect to be a damn finger, you were like the surprised monkey meme. You heard that your boyfriend was very hurt, too much, and you immediately went to see his situation, you talked to Sensei Gojo about him... and he explained the situation more to you... ITADORI ATE A DAMN FINGER-

You didn't know what to do anymore... and possibly after Itadori gets better, you scold him.

You waited for him to get up.. and when you did, you prepared to shout the million scoldings at him.. but it was so sudden that your "boyfriend" got up and stretched out laughing.. you noticed the changes in his face and the strange tattoos that he had on certain parts of his body... and you were speechless.

Your boyfriend.. no.. Sukuna, he saw you and immediately made fun of you.

"Hey brat, what the hell are you doing watching me?" That smile and that way of speaking to you... your boyfriend would NEVER say such barbaric things to you.
