The scent you left behind

In a world where Alphas, Betas, Omegas, and the rare Enigmas coexist, scent is impossible to forget.

Bang Chan (25) is an Enigma, a rare secondary gender that few people truly understand. Calm, respected, and impossible to read, he's used to people being drawn to him-but one stranger leaves an impression even stronger than his own scent.

At a college party, Chan spends one unforgettable night with a mysterious Omega before the boy disappears without leaving his name. All Chan is left with is the lingering scent that refuses to fade from his memory.

That Omega is Kim Seungmin (22).

Determined to pretend the night never happened, Seungmin throws himself into college life alongside his best friends-Han, Felix, and Jeongin. He never expects to cross paths with the older Enigma again, especially not when they end up sharing the same campus.

As Chan searches relentlessly for the Omega he can't forget, fate keeps pushing them together. But the more they learn about each other, the more secrets begin to surface. With loyal friends, complicated emotions, and the expectations that come with being an Enigma and an Omega, they'll have to decide whether their connection was only meant to last one night-or if it was always destined to become something more.
