Choi Yu-jun was trained from the moment he could walk. Every laugh, every tear, every instinct erased and replaced with precision, discipline, and cold efficiency. At fifteen, he is the perfect assassin. Untouchable, invisible, lethal. His life is a series of missions, each one cleaner than the last, every emotion suppressed... until a new assignment shatters everything he thought he knew about control.
Seoul is the stage for his next target: a K-pop idol named Kang Seo-jin. Charming and magnetic under the lights, Seo-jin conceals a world that no fan ever sees, a grumpy, sharp-edged young man who battles expectations, exhaustion, and secrets behind the camera. To everyone else, he is effortless, funny, untouchable. To Yu-jun, he is dangerous in a way no weapon could ever measure.
To complete the mission, Yu-jun infiltrates Seo-jin's life under the guise of a manager, stepping into rehearsals, late-night schedules, and glittering performances. But the closer he gets, the more lines blur: the target isn't just a person to manipulate or deliver, it's someone who can awaken what Yu-jun has spent his life denying: feeling. Desire. Doubt. The flicker of a heart that refuses to obey.
In a world where killing is permitted and emotions are forbidden, Yu-jun must navigate the most dangerous territory of all, love. Every smile, every laugh, every stolen moment pulls him further from the perfection he has been taught to uphold. And the deeper he falls, the higher the stakes: for him, for Seo-jin, and for the organization that will not forgive weakness.
A story of obsession, danger, and forbidden desire, Killing is Permitted, Feeling is Too asks one impossible question: can a man trained to kill survive a heart that refuses to stay silent?
~~
Or: a story about how even the greatest man, without doubts, can fail.
