Bound by Instinct

In Bound by Instinct, desire isn't something you choose - it's something that finds you in the dark and refuses to let go.
Sakusa Kiyoomi, a disciplined and cold-blooded alpha known for his control and precision, has spent his life building walls higher than his instincts can climb. Emotion is a liability. Bonds are distractions. Attachment is a weakness he cannot afford.
Until Miya Atsumu walks in like a disruption wrapped in sunlight and smoke.
Atsumu, an omega who refuses to be defined by softness or submission, carries a reputation just as dangerous as any alpha. Sharp-tongued, unpredictable, and impossibly magnetic, he doesn't ask for protection - he challenges it. And worse, he awakens something in Kiyoomi that logic can't silence.
Their first meeting shouldn't mean anything.
Their second changes everything.
In a world where instinct dictates hierarchy and bonds are often written in force rather than choice, Kiyoomi finds himself drawn into a connection that feels less like romance and more like gravity - relentless, consuming, inevitable. Atsumu, meanwhile, discovers that behind Kiyoomi's icy restraint is a devotion so intense it borders on possession.
But instinct doesn't come without consequence.
As outside forces close in and the rules of their world tighten around them, the line between protector and captor begins to blur. Because in this story, bonds aren't chosen.
They're claimed.
And once claimed... they don't let go. 🖤
