Summary: Y/N has wanted nothing more than to see her boyfriend's demon form. So what better gift than to surprise her with it on her birthday? Warnings: Cussing, implied smut PG-13. You are responsible for your own media consumption. Dedicated to: @redvexillum
Dating a demon wasn’t nearly as chaotic as movies made it out to be. In fact, for Y/N, it was almost annoyingly normal. Apart from the absurdly hot supernatural boyfriend, of course. Jinu, center of the K-Pop sensation Saja Boys and secretly a demon, was sweet, attentive, and somehow more romantic boyfriend than any human she’d ever dated. Even if he was rarely around.
It had been close to six months of a near perfect relationship and Y/N had gotten used to the long stretches of absence, the whirlwind tours, and the cryptic texts like ‘Just finished stealing some souls. Miss you.’
She didn’t mind too much. She had her own life, her work, her routines, but some nights felt hollow. The lack of warmth beside her in bed, laughing and moving to show a meme to a phantom of someone no longer there, no shared meals. Phone calls helped, though. His voice, warm and playful even when exhausted, always made her feel less alone. His sassy smile, gleaming over at her through the phone, could make even the worst day better. But it still hurt. To have someone she loved so deeply essentially destroy the world. It’s not that she didn’t understand…it’s just that she really didn’t. Y/N had never seen the demonic side of Jinu, her boyfriend adamant that she did not. But she couldn’t help herself, being so curious. One of those nights, curled up in bed with the glow of her phone on her cheek, she let something slip.
“I know you don’t like talking about it, but... I want to see you in your demon form. Like, just once. Is that weird?”
There was a pause on the other end. A long one.
“Y/N… it’s not something I show people. It’s not just makeup and cosplay—it’s intense. Dangerous, even.”
“I’m not scared of you.
“You should be.
She could tell he was half-joking. But then he changed the subject, and she figured that was the end of it. Except it wasn’t.
Y/N’s birthday arrived on a sleepy Sunday morning, sun pouring through her apartment windows. She hadn’t expected anything too dramatic. Maybe dinner later, maybe a sweet text in the morning. After all, he was busy. Demon boyfriends with sold-out arena tours usually were. Which is why the knock on her apartment door startled her. Rubbing her eyes, slipping on a fluffy purple robe, Y/N padded to the door and looked through the peephole. Upon seeing the blurry form, she immediately opened the door with a shocked gasp.
“Jinu?!”
He stood there with the boyish grin that melted a million hearts, holding a massive bouquet of dark red roses and a box of handmade chocolates shaped like little crescent moons.
“Happy Birthday, darling.”
Before she could say anything else, he stepped inside and caught her in a hug, spinning her off her feet in the air as she squealed. She clung to him, laughing, overwhelmed with joy, her heart blooming wider than the roses in his hands. It all felt like a perfect dream.
“I thought you were in Tokyo!” she said breathlessly as he set her down.
“I was. Red-eyed straight here just for you.” He kissed her forehead. “And I’m not going anywhere today.”
Though it seemed impossible, Y/N broke free of his grasp and immediately grabbed the giant bouquet from her lover’s hands. She practically floated into the kitchen, already grabbing a vase for the flowers, slightly deliberating which one would suit the room and buds best. “You didn’t have to…Well, I wanted you to…but this is already perfect.”
Jinu came up behind her, wrapping his arms slowly around her waist. His breath ghosted over her ear like a promise. “I am glad you like it. But I have something else for you, too.”
She blinked. “I…what do you mean?”
“Oh, darling,” he purred. “Just you wait.”
She turned around, ready for maybe another gift or a shirtless partner (He had a…drive after all). But to her surprise, where her boyfriend had been, sweet, dark-haired, boy-next-door Jinu, now stood something entirely else. Towering a few inches taller than usual, his skin shimmered a smooth, dusky violet hue. Black patterns curled like living tattoos down his arms and neck. Those golden eyes, molten and slitted like a predator’s, pinned her in place, glowing. His mouth curled into a smirk, revealing perfect, gleaming fangs. Her knees buckled.
“Holy shit,” she whispered.
“Language,” he teased with a wink, but his voice was deeper now, layered with something ancient.
She reached for the counter blindly, dazed. “You’re… you’re…”
“Still me.” He stepped closer, eyes boring into hers with a soft vulnerability. “But this is what you wanted, right? To see me like this?”
She made a noise somewhere between a gasp and a moan. “I… I didn’t think you’d actually…”
He chuckled lowly, and the sound rippled through her and down her spine. His arm reached out to encase her form between his warm body and the cold countertop.
“Had to wait for the right time. And what better time than your birthday, hm?”
She reached out with trembling fingers, brushing one of the glowing patterns on his collarbone. It pulsed gently under her touch, and she watched how Jinu’s eyes nearly rolled back into his head.
“I am going to….faint.”
He leaned down, his lips hovering above her neck, those sharp fangs ever so slightly grazing the supple flesh beneath them.
“Please do. I’ll just catch you.”
She laughed, half-dizzy, fully lovestruck, and entirely undone. “Best. Gift. Ever.”
“Good,” he murmured. “Because I now I think it’s time I unwrap my gift.”
So long to a calm, romantic dinner….
