Fifteen years ago, the brutal murder of a powerful casino chairman became one of the country’s most infamous unsolved cases. The man accused of the crime disappeared, leaving behind only his young son, Lee Chae Ha, who grew up carrying the stain of being known as the killer’s son. On the other side of the tragedy was Joo Tae Seon—the victim’s son—who devoted his life to becoming a prosecutor, believing justice meant making someone pay for what was taken from his family. Fate reunites them when Chae Ha is assigned to work under Tae Seon, forcing the killer’s son and the victim’s son into an uneasy partnership neither of them wants. Tae Seon treats Chae Ha with cold contempt, constantly questioning his motives and reminding him of the blood tied to his name, while Chae Ha silently endures the cruelty, convinced he deserves every accusation if it means uncovering the truth. As they investigate the long-buried case, hatred slowly twists into obsession. Every revelation binds them tighter, blurring the line between justice and revenge. Tae Seon cannot decide whether he wants to destroy Chae Ha or keep him close enough to watch him suffer, while Chae Ha finds himself unable to walk away from the only man who has every reason to hate him. Together, they descend into a web of corruption, betrayal, manipulation, and buried secrets, where every answer forces them to question whether the real killer has been hiding in plain sight—and whether their growing attachment is built on love, guilt, or the desperate need to ruin each other before the truth finally does.
