A Case of You (Yuji Itadori x OC) AU

Sukuna

When Sukuna opens the door, his frowning face stumbles upon the female Fushiguro. His eyes narrow and a wicked smile crosses his lips.

"Yuji isn't here." He drawls, grinning.

"I'm here for you." Her shoulder slams into him as she pushes past him. Too bold even for her.

Oh.

"What do you want Me-gu-mi."

Her hot gaze burns and Sukuna bathes in that fire.

Their biological father didn't bother with their names when the twins were born, naming both son and daughter Megumi.

Sukuna found it hilarious. "Call one, two show up."

It annoyed her.

"Why did you tell me about Yuji?" Heavy gaze of her dark eyes amuses him.

"Oh, I shouldn't have?" Venom seeps through his voice, but this is Sukuna. He is poisonous. Dangerous. He hovers over her like the king cobra. "What a shame."

Hot breath tickles her face.

"I thought you should know whom you are sucking face with."

Her eyes widen in shock.

Body turns cold.

Sukuna knows.

"Ah," the grin of a madman. "Yes, yes. I know about your little secret." His fingers trace her cheekbones.

"How?" Staying calm is impossible. Her voice trembles treacherously.

"Next time you decide to shove your tongue down his throat, make sure no one is home." Sickening sweet voice makes her want to disappear.

Ignore him.

Ignore.

"It wasn't your place to tell." She manages to let out.

And Sukuna laughs.

Loudly.

Madly.

Like he just heard the funniest joke.

"My place?" He tries to catch his breath. "You are hilarious."

Umi glares. Anger rises quickly. "For the past eight years, this daft punk has been looking at you like..." Sukuna stops trying to find the right words.

"Like what?" Her mouth becomes dry. The voice sounds lifeless.

He smirks. The tattoos on his face stretch. Sukuna is intimidating.

"I'll leave that to your imagination, Me-gu-mi-chan."

"You are despicable."

She turns on her heels to leave when Sukuna's strong grip yanks her back.

"Tell me something." His hands hold her shoulders firmly. "Please my curiosity." He continues. "By any chance, when you were kissing Itadori, were you imagining me?"

Her eyes widen. Umi turns pale.

And Sukuna...

Sukuna understands.

His lips stretched in a bloodthirsty smile.

Thoughts rummage through her head, but she cannot not hold onto any of them.

She feels dirty.

Disgusting.

Umi wants to run. Away from Sukuna's piercing red eyes. Away from his bloodthirsty smile.

Away from everything.

"I almost feel sorry for the punk." The fake pity in his voice makes her nauseous. "Pitiful bastard."

No.

Yuji is not the one who is pitiful.

She is.

"How about a kiss with the original? Hmmm? So, you have something to compare him to." he leaned closer to her face. "I promise, you'll love it."

"Move." she says coldly.

Sukuna didn't budge.

"Sukuna, move."

"Hmm? Why? Not interested? Tsk...what a pity. And now that you are finally eighteen."

Her grimace makes him laugh.

"Or is Yuji that good?" He rubs his chin. "Hmm doubt it. Pretty sure all his previous girls were imaginary."

Her lips stretch into a thin line. She takes a step closer. Sukuna looks at her completely relaxed. He watches her lips twitch as she attempts to say something, but she doesn't.

He is having fun.

"My regards to Yuji." His grin is a mixture of malice and torment. Suddenly he leans forward, locking his teeth on the sensitive flesh of her neck. Hard. Painful.

Without hesitation her first connects with his face.

"Ow," Sukuna's tongue traces his teeth as metallic taste fills the mouth. "Pretty well-placed punch." He says slowly, moving his jaw side to side. "You lack strength though."

Umi continues clenching her fists; her dark eyes drill his face.

Unbearable.

She pushes past him and makes her way to door.

She stops for a moment.

Come on. Turn around Me-gu-mi-chan.

Sukuna is waiting.

Anticipating.

But she does not.

The door shuts quietly, leaving Sukuna alone.
