[OT7!Hybrid!BTS x Hybrid!OC]

Elysian has spent her whole life inside the walls of Hanwol Hybrid Support Center - a quiet, structured sanctuary where routines are safe, smiles are gentle, and nothing ever changes.
For a doe hybrid with soft instincts and a softer heart, Hanwol is the only world she's ever needed.

Mark, the man who rescued her as a child, works there.
Lives there.
Protects her there.

And Ely trusts him with every beat of her small, fluttering heart.

But the morning Jungkook arrives, everything shifts.

He's a rabbit hybrid who doesn't act like one - silent, watchful, scented like cedar and rain. He studies every hallway, every locked door, every flicker of the lights. And he watches Ely most of all, his dark eyes following her with a focus she doesn't understand.

Ely feels it too - a strange warmth in her chest, a flutter in her stomach, an instinct she can't name.
She doesn't know why she keeps looking for him.
She doesn't know why he tenses every time her collar glints in the light.
She doesn't know why the facility's electronics keep glitching whenever he's near.

Mark says it's just the generator.
Mark says everything is fine.
Mark says she should stay close.

But the lights keep flickering.
Doors keep clicking.
And Jungkook keeps watching the building like it's a trap waiting to spring.

Ely has never questioned Hanwol.
Never questioned her collar.
Never questioned the medical wing door that no one ever returns through.

Not until now.

Because the day Jungkook arrived was the day the walls of her safe little world began to crack -
and the truth waiting behind them is nothing she's been prepared to face.
