Sukuna is a scary-looking man, no one would expect him to be a devoted fan of a girl group.
He’s obsessed. He listens to every comeback, watches every music award show, watches every interview, buys every album, attends every concert, wins every fan call, and attends every meet-and-greet. And lucky you, you're his bias. The way your hair would bounce with the movement of the choreography and the bright smile you had on your face when talking to your fans made him fall in love.
His nephews feared their short-tempered, scary uncle was losing his mind when they found his stash of photocards of you, a cute idol whose music demographic is teenage girls.
You’ve seen Sukuna frequently at fan events, and he’s become a regular to you. You don’t mind it, it feels like a blessing to be able to interact with a handsome man like Sukuna instead of some greasy, neck-bearded weirdo.
It’s another fansign in Sukuna’s town. It’s gotten to the point where you're excited to see him, as if he is an old-time friend. Sukuna loves fansigns because he gets to speak to you, obviously, but he hates seeing gross guys flirting with his bias, his idol. He has studied your mannerisms enough through speaking to you and watching interviews to know when you're uncomfortable. He notices the way you look away when you get told something strange, or the way you cough when you don’t want to answer a weird question. He knows you more than any of the losers in here (even if he's a loser too).
Sukuna bites his tongue because this is the part that's worth it, being face to face with you. There’s only a table in the way of you two, the line of professionalism, a line you dare not cross. Your eyes instantly light up once you see Sukuna's naturally grumpy face. “Kuna~~!” You exclaim the nickname you created for him. You grab his hand with both of your comparably small hands and bring them close to you in excitement. “I missed you, Kuna~~ I thought you weren’t going to show up, I almost got really sad.” You pout dramatically. Sukuna’s face and ears are bright red.
You looked flawless, as always. Wearing a dazzling outfit your stylist chose for you, which probably cost more money than your rent. Your skin is clear like glass. Sukuna swears he can see his reflection in your cute cheeks. “Oh- um- I’m here now.” He says, looking everywhere but into your eyes. Not one lady in Sukuna’s entire dating life has gotten him flustered as if he were a preteen boy like you did.
“Ah! Kuna!” You say like you made a discovery. You grab his hand and press it against yours, comparing hand sizes. “Your hands are soo big~ You could be a bodyguard.” His face turns bright red. He knows for a fact those mouth breathing losers are seething at the fact that he’s touching you - No, you’re touching him. You play with his fingers delicately as if he were a toy to play with for your enjoyment. “Your tattoos and your strong muscles~ all the creeps would be so scared of you.” You coo, obviously oogling the man in front of you. “You’re the only one I’d want to protect.” He mumbles shyly under his breath, uncharacteristic for him. “Kunaaa~ you’re such a flirt.” You squeal, embarrassingly, a little too loudly. “I don’t know why you don’t have a girlfriend yet.” He shrugs in response. He knows why he doesn’t have a girlfriend, it’s because he spends all his free time obsessing over you.
He slides the album he bought close to you. “Would you mind signing this? And dedicating it to me, please?” He looks at your face when asking you, making you hot. “Of course!” You leave your signature on the album cover, then write ‘Kuna’ inside a heart. You pick up the album and bring it to your lips, staring Sukuna straight in the eyes as you do so. You left a big lipstick kiss mark right next to ‘Kuna’s name. Sukuna heard his heart beating rapidly. He nonchalantly adjusts himself in his seat as if you didn't just give him the moment he's going to replay every night.
“Kuna~ I was actually wondering if you could sign something for me this time.” You ask shyly. He looks at you with an interested expression. His eyebrows furrow in confusion, his exterior is angry-looking, but his intentions are pure.
You pull an orange Manila envelope from under the table. One of your members sitting beside you glances at the envelope, then at Sukuna, then at you. She has a hard time keeping in the laugh threatening to leave her lips, causing Sukuna to worry. You nudge your member with your elbow, signaling her to focus on the fan in front of her.
You slide the envelope over to him. He gulps as he picks it up and opens it. He slips out the single piece of paper inside. His eyes widen when looking at it, and his face goes as pink as his hair. At the top of the paper reads “Non-Disclosure Agreement (NDA)” in big, black, bold letters. His wide eyes travel from the paper up to your face. You’re looking at him with nervous anticipation. Twiddling your thumbs and tapping your foot fast. ‘real cute’ he thought.
“I’m- I’m sorry. It’s my first time giving someone one of those. YouknowiunderstandifyoudontwannasignitIjustthoughtbecause-“ you babble before the beefy man in front of you cuts you off. “Princess,” He calls you with a smirk. His hand was held out like he was asking for something. You hold your breath, your anxiety making it feel like you’re underwater. “The pen?” He says, pointing at his open hand with his eyes. “Oh!” You say under your breath, frantically placing the pen in his hand.
He bites the cap of the pen off, keeping the cap in between his teeth. He places the pen on the paper where he’s supposed to sign. He looks back up at you, holding eye contact. It’s cute how a scary-looking guy like Sukuna can get such a picture-perfect idol like you flustered. Your nervous state makes him chuckle under his breath.
“You said it’s your first time giving out one of these?” You nod frantically. He smiles to himself, “Lucky me.” He says, writing his signature as 'Kuna' at the bottom of the paper.
