Chapter Text
There are rules in this city.
Some are written — carved into legal code, stamped with seals, reinforced with surveillance towers that hum above the subway lines. Others are older. Passed down in whispers. Enforced with teeth.
Rule One: An Omega without a bond is a danger.
To others, they say. But mostly to themselves.
Rule Two: An Alpha who loses control will be put down like a dog.
Unless they have money. Or a famous surname. Or friends on the inside.
Rule Three: Betas are neutral. They keep their heads down. They make coffee. They don’t ask questions. They walk between worlds and leave no scent behind.
It’s always been this way — or close enough that no one remembers otherwise. The old instinct laws were codified in 1987 after the Gangnam Heat Incident. A diplomat’s son went into rut on a city train. Three Omegas dead. Two officers infected. Now, heat suppressants are government regulated. Rut licenses are reviewed quarterly. Mating is a contract with terms and penalties. Love is… optional.
The government calls it “instinct regulation.”
The underground calls it bullshit.
But what no one talks about — at least not in courtrooms or televised debates — is how all these laws only matter if you’re seen.
And most people like Jungwon are good at staying invisible.
Born Omega? You’re clocked at birth, microtagged before you turn one, dosed before puberty. Your parents can opt into the state’s subsidized bond program — basically an arranged mating service dressed up in paperwork. If you’re lucky, you get matched to a kind Alpha, one who pays for your scent control and never raises a hand. If you’re unlucky… you learn to lie early.
Or you disappear.
Jungwon disappeared around the age of sixteen. Started Beta-passing by seventeen. Applied to a government-run corporate training program at eighteen using forged scent reports. He thought he was safe.
Until his body betrayed him. Until the heat came — raw, roaring, and days early.
Until Lee Heeseung found him in a half-collapsed bathroom stall, shivering with shame and slick, trying not to cry.
Now here’s something the rulebooks don’t cover:
Black-market heat contracts.
They’re illegal. Exploitative. Dangerous.
But also? Voluntary.
For some Omegas, it’s the only choice they ever get to make.
A contract like this means giving your body to an Alpha for the duration of a heat in exchange for money, meds, housing, and — for the lucky ones — privacy. No bond mark. No ownership. Just a signature and a bite that fades.
Heeseung offered Jungwon such a contract.
Jungwon signed it with shaking hands.
And so here we are.
A contract signed in scent and sweat. A city that looks clean on the outside but bleeds rot in its alleys. Two people who should never have met — bound not by love, not yet — but by the terrifying, trembling desire to be seen.
The rulebook never said what to do when your Alpha starts whispering your name like a secret.
The law never prepared Jungwon for wanting it — even when it hurt.
And Heeseung…Heeseung has always followed the rules. Until now.
This city doesn’t forgive the ones who stray. But that’s the thing about instinct.
Once it’s awake — it never sleeps again.
