From the moment Jungkook..25 years old...stepped into the lavish Kim residence, he knew he was screwed. Not because of the fancy chandelier or the expensive scent in the air.

No..no.. it was because of the man who opened the door. Kim Taehyung. 40 years old. Broad-shouldered. Elegant in a black silk shirt, half-buttoned like he didn’t care. Hair slightly tousled, a glass of red wine in hand like he was born to own the world.

Jungkook's breath caught. No fvcking way. That was his boyfriend’s father? FATHER??

Well, not a biological father. But still... father. And Jungkook had the audacity to blush.

Taehyung didn’t miss it. He tilted his head slightly, eyes dark and amused. “You must be Jungkook,” he said in that smooth, deep voice. “Jihoon talks a lot about you.”

Jungkook smiled, polite. “I hope good things.”

“Hmm,” Taehyung hummed, smirking as he stepped aside. “We’ll see.”

That was the beginning of it all.

Dinner was a blur. Jungkook sat beside Jihoon ( 24 years old ), smiling at all the right moments. Jihoon, ever the sweet, clueless guy, kept talking about school, films, future plans. But Jungkook’s eyes? They kept drifting to the man at the head of the table. Taehyung. Effortlessly composed. A silver ring on his finger, long fingers tapping gently against his wine glass. His gaze would occasionally lock with Jungkook’s across the table. Not by accident. There was something deliberate about it... like he knew exactly what he was doing.

And maybe he did.

Because Taehyung wasn’t new to attention. He'd seen Jungkook before--once at a university event where he was invited as a guest speaker. Back then, Jungkook was on stage, laughing with his classmates, full of life and charm. Taehyung had noticed him. Sharp jawline. Mischievous smile. That knowing twinkle in his eye. But he hadn’t done anything, of course. He was just there as a guest. Nothing more.

Then, months later, the same boy showed up at his door… as Jihoon’s boyfriend.

God really had a sense of humor.

And Jungkook? Oh, Jungkook didn’t hide it well. His eyes kept scanning Taehyung like he was art. The boy was trying hard not to be obvious, but the way he bit his lip and glanced at Taehyung when Jihoon wasn’t looking—Taehyung saw it all. And he enjoyed it. Maybe a little too much.

Jungkook was just his type. Young, beautiful, bold underneath all that polite charm. Taehyung could smell the curiosity radiating off him. Like he wanted to explore him. Learn him.

Touch him. Hold him.

Taehyung shouldn’t think like that. Jungkook was technically off limits. But honestly? He wasn’t even Jihoon’s real dad. Jihoon was the child of his cheating ex. Back when Taehyung was 20, in love and stupid, he thought he’d found his future with a woman who ended up pregnant---with another man’s child.

She lied. Said it was his. Tried to trap him.

But Taehyung wasn’t a fool. He found out. Walked away. Refused to take responsibility for a child that wasn’t his. She cried, begged. Said she had no one else. That the real father didn’t want the baby. That she’d be ruined. Ruin the baby too. She had no money, no family, no backup.
