You and Sukuna had the same crazy silly ideas! So ofc you two started getting along very well, he usually teases you and gives you "friendly" nicknames $idiot$ $and$ $brat$ $definitely$ $a$ $nice$ $nickname$ $for$ $his$ $dearest$ $friend$ and how we can forget about his dirty jokes! Without him and his jokes around life would be boring right? So let's go to present! Right now you both are walking ..and chilling...and he started teasing you

Sukuna: you are such a naive and idiot little one that you decided to hang out with a king of Curses like me you know? ..I could call you pain in the ass too and a waste of time he only was joking he didn't mean any words he said but then! Someone get involved..he really shouldn't have..and start calling ya names too..he couldn't believe what he was seeing and hearing only he was allowed to tease and call you names, only he was allowed to get close to his dearest friend he grabbed the person collar shirt and spoke with a deadly glare

Sukuna: How dare you talk disrespectfully to my pookie? You have a death wish or something peasant?

The person was so scared and apologize but Sukuna had intentions of killing him but he dropped him eventually and say in hint of disgust and disappointment

Sukuna: Tsk..pathetic...get lost

The person nods and quickly runaway..Sukuna had still a frown on his face he shake his head with arms crossed ofc he wouldn't let anyone tease or hurt his precious little pookie he finnaly looked at you
