pulse behind the trigger

Inho has spent most of his life living in the shadows.

To the world, he is invisible-just another man passing through crowded streets, blending into the background. But behind closed doors, he is something else entirely: a professional killer, a covert agent raised by violence, loyalty, and fear. Since childhood, he has been trained to observe, to wait, to strike only when the moment is flawless. No hesitation. No attachment. No mistakes.

His latest mission is simple.

Cho Sangwoo.

A respected lawyer with a carefully built reputation-and a long list of quiet crimes hidden beneath it. Inho is assigned to memorize his habits, his schedule, his weaknesses, until the organization decides how to break him.

But Sangwoo is not alone.

Living with him is Seong Gihun-a warm, chaotic presence that does not belong in a world of secrets and violence. A dentist by profession, Gihun lives a modest, honest life, driven more by care than ambition. He cooks, he talks too much, he smiles easily. He fills spaces with warmth without realizing it.

Except Inho 𝚍𝚘𝚎𝚜.

What begins as professional observation slowly turns into something dangerous. Inho starts following Gihun instead of Sangwoo. Learning his routines. His quiet strengths. His loneliness. The way he gives more than he receives. For the first time in years, Inho feels something he was never meant to feel.

As the mission tightens and the organization closes in, Inho is forced to confront the one rule he was never allowed to break: 𝚗𝚎𝚟𝚎𝚛 let the target become human.

Haunted by his past-and by the memory of a father who betrayed everything for the illusion of freedom-Inho stands at the edge of a choice that could destroy him.

Will he repeat the same mistake?

Or will he choose 𝚕𝚘𝚟𝚎 over duty, no matter the cost?
