The air in the Choi mansion was quiet that afternoon. Golden light streamed through the large windows, warming the polished wooden floors. Somewhere far off, the faint sound of a grand piano being tuned echoed through the halls.

YN had just finished her online lecture-barely surviving the boredom of economics-and was lazily wandering the corridor with a peach soda in hand. Her bare feet padded softly against the floor as she passed the guest wing where Jungkook was staying.

Her earbuds were in. Her playlist was loud. And her attention span?

Non-existent.

She stopped outside a door that was half-ajar.

Jungkook's room.

For a second, she stared at the small gap. He was always so guarded, so distant. She couldn't even guess what kind of person he was outside his broody, bodyguard façade.

Curiosity bloomed.

Maybe he's the kind of guy who plays guitar alone or secretly collects vintage perfume bottles, she thought sarcastically, pushing the door gently.

She didn't knock.

Didn't think twice.

And the moment she stepped in, she froze.

Jungkook stood with his back to her, shirtless.

The black fabric of his t-shirt was in his hand, mid-air, as he pulled it over his head-but he didn't rush, didn't cover up like most people would.

In fact...

He didn't move at all.

The silence between them thickened.

Time slowed.

And all YN could see was his back.

Smooth, sculpted muscles rippling under the dim golden light. Broad shoulders. A body that looked carved from shadows and steel.

But it wasn't just his physique that left her staring-it was the tattoo.

Stretching across his entire back in black and grey ink... was a hauntingly detailed Medusa.

Her eyes were covered with a blindfold, mouth parted as if mid-scream, and instead of snakes crawling outward, they were wrapping back into her own body, twisting like shackles.

It wasn't just a tattoo.

It was a story.

And it made her shiver.

She blinked. "Whoa... What kind of tattoo is that?"

Still facing away from her, Jungkook spoke.

His voice was low. Cold. Controlled.

"Next time, knock before entering."

A beat.

"I don't like people involving themselves in my privacy."

His words hit harder than they should have. Not because he yelled-he didn't.

It was the tone.

Detached. As if she didn't even exist in his world.

YN's mouth parted slightly. "I-I didn't mean to-"

He slipped his shirt on slowly, still not looking at her.

"Then learn to mean it next time."

Her shoulders tensed. The confident, bratty mask she wore so easily began to slip.

She lowered her gaze, and for once, her voice softened.

"...Sorry," she mumbled.

And then, quietly, she turned and walked out of the room, shutting the door behind her without a sound.

--

Inside, Jungkook finally exhaled, his jaw tight.

He hadn't expected her to come in.

Hadn't meant for her to see that part of him.

The Medusa tattoo wasn't fashion.

It was rage.

A symbol of betrayal, loss, and the darkness inside him that he couldn't kill no matter how hard he tried.

It was the last thing his mother sketched on her notepad before she was murdered.

A myth twisted by pain. A message frozen in ink.

He closed his eyes.

"She shouldn't have seen that," he whispered to himself.

Not because he was ashamed.

But because the further YN got from him, the safer she'd be.

--

Meanwhile, YN sat in her room, unusually quiet.

She stared at her drink, not sipping it.

Her mind was still stuck on that image-Medusa's blindfolded eyes, the dark shadows swirling like silent screams.

And Jungkook... the way he stood there, still and distant, as if no part of this world could touch him.

"Who are you really... Jeon Jungkook?" she whispered to herself.

And for the first time since he arrived, she wasn't thinking about making him quit.

She was thinking about what he was hiding...

And why it hurt a little to be pushed away by him.

The morning sun painted the sky in hues of soft peach and grey, but inside the Choi mansion, there was no warmth.

Only tension.

A heavy silence had settled over the dining table where the family's usual luxurious breakfast had been served-gold-trimmed plates, silver cutlery, a line of freshly brewed tea and juices, untouched.

Choi YN sat stiffly in her chair, her spoon clinking against the side of her cereal bowl. She wasn't eating. She wasn't even pretending to. Her jaw was clenched, her eyes sharp as they glared at the man sitting across from her.

Choi Sejin.

Her father.

Her cage.

He was busy reading the morning newspaper, pretending to be unaffected.

But the tension was crackling.

Jungkook stood silently near the archway, arms crossed behind his back, observing without emotion. His job wasn't to interfere. Only to protect.

But even he could feel it-something was about to explode.

YN finally slammed her spoon down.

The sharp clang made both Sejin and the nearby staff flinch.

"Are you seriously going to ignore me again, Dad?"

Sejin folded the newspaper, slow and deliberate. He didn't look angry. He looked... bored. "We've talked about this."

"No," she said sharply, standing up.

"You talked. I sat there like a statue while you made all the decisions."

"I'm your father," Sejin replied calmly.

"It's my job to decide what's best for you."

"You think stopping me from seeing Grandpa is what's best?" she scoffed. "You think lying about his health and keeping me away for two years is protecting me?"

Jungkook's eyes flicked up at that.

Two years?

"Your grandfather lives a quiet life. He asked for distance after your mother passed. It's not my fault he left," Sejin said, taking a sip of his coffee.

"Don't twist it," YN snapped. "You made him leave. After Mom died, you treated him like some outsider. You didn't even let him speak at the funeral!"

"That's enough."

"No!" Her voice rose, breaking through the stiff elegance of the breakfast hall.

"You've lied to me every time I've asked! Every time I said I missed him, you told me to focus on school. Every time I begged, you told me he was 'fine.' But I haven't seen him. I haven't hugged him. I haven't even heard his voice in two years!"

Sejin stood slowly, fixing his cufflinks. "This conversation is over."

YN's eyes welled up-not with weakness, but rage.

"You're not protecting me. You're controlling me. And I'm sick of it."

"Don't speak to me like that in front of staff," Sejin said coldly.

She ignored him.

Her voice cracked slightly. "He's the only piece of my mom I have left. You buried her, and then you buried him too."

And with that, she turned on her heel and stormed off.

Jungkook didn't move, but his eyes followed her.

He heard the stomp of her bare feet on the marble stairs.

Then the slam of her bedroom door.

Then-

Click.

The sound of the lock turning.

Silence returned.

Jungkook turned slightly toward Sejin. "Should I-"

"No," Sejin cut him off. "Let her sulk."

"She said she won't eat."

"She'll get over it. She always does."

But Jungkook, even with his hardened heart and icy soul, felt something stir.

Not sympathy.

But recognition.

That deep ache of being shut out.

That feeling of love being treated like a liability.

He glanced up the stairs. The hallway was empty now, quiet as a grave.

Inside that locked room was a girl who wasn't just spoiled.

She was grieving something she had never been allowed to heal from.

A grandfather who'd been erased.

A mother whose memories were locked behind political appearances and cold rules.

Jungkook didn't know the full story.

But now, one thing was clear-

This family was hiding a lot more than secrets.

And YN?

She wasn't just another rich girl throwing tantrums.

She was broken in places he hadn't yet seen.

And maybe... just maybe...

That made her more dangerous to his mission than he realized.
