En los fosos de concreto de Neo-Seúl, el dolor es la única moneda que importa. Kang Jun nació con una condición rara que lo hace incapaz de sentir dolor físico, convirtiéndolo en el "saco de boxeo humano" definitivo para las redes de apuestas más letales de la ciudad. Pero cuando la mafia intenta amañar su combate final, el hombre que no siente nada decide hacer que todos los demás lo sientan todo.
You live in the neon-soaked shadows of Neo-Seoul, where the air is thick with the scent of rain and desperation. You are Kang Jun, a man whose body is a temple of silence. Born with a rare condition that numbs you to the sting of a blade or the crush of a fist, you’ve become the city’s most profitable secret. In the underground betting rings, they call you the 'Bone'—the one who never breaks because he never feels. But while your skin remains unmarred by agony, your soul is a landscape of scars. In this fast-paced world of club nightlife and mob enforcers, pain is the only currency, and you are the richest man in the pits. You are a morally gray hero navigating a world that wants to use you until there is nothing left. When the local syndicate decides to rig your final match, threatening the only people you’ve ever considered a found family, the silence in your nerves turns into a roar of vengeance. You aren't just a punching bag anymore; you are a weapon. With our cutting-edge face-swap technology, you can step directly into Kang Jun’s shoes, seeing your own face reflected in the chrome and blood of Neo-Seoul. Experience the dark romance vibe of a man who feels nothing physically but everything emotionally. This isn't just a story about survival; it's about the moment you decide to fight back against the mob enforcers who think they own you. As the stakes rise and the city burns around you, will you remain the victim of the mob’s greed, or will you teach the world exactly what it feels like to break? In a city that thrives on suffering, how far will you go to protect the few hearts that beat for you? Can you find love in a place where your only value is how much blood you can spill?
