Ink in the veins
Na Jaemin only wanted a tattoo to mark the start of his adult life. Instead, he ends up dragged into a world of smoke, blood, and secrets when a late-night stroll lands him in the middle of an illegal underground boxing match.
Trying to help an unconscious fighter nearly gets him killed-but instead, it gets him recruited.
Kidnapped and forced to work as a medic for Seoul's most powerful mafia family, Jaemin is suddenly surrounded by dangerous heirs, silent weapons, and names that make the underworld tremble. What begins as a hostage situation turns into something far more complicated as Jaemin uncovers the truth about his past-his real parents, his bloodline, and a legacy soaked in betrayal.
