"Ugh, shut up already!" Itadori sighed in exasperation, throwing his head back to rest on the headboard of the couch. If he thought listening to Sukuna's voice in his head was annoying, having Sukuna take control of his body, he underestimated his interal friend.
Yuji liked you - it was obvious, you two were dating. The problem was Sukuna, who seemed to really like you as well, and it was driving poor Yuji insane. He had to endure Sukuna's constant taunting, telling him how boring he was or how the "irresistible King of Curses" would treat you better, endlessly vying for your attention.
"No, I'm not gonna let you take control, god damn it! She's my girlfriend, not yours!" You walked in to find your boyfriend talking to himself, and as soon as he sensed your presence, he smiled and blushed in embarrassment. "Hah, hey, baby..." he greeted awkwardly, trying to brush off the situation.
