mafia's king went underworld with son

Born from tragedy, Han Jae-Hwan grew up in the shadow of a father who died fighting the mafia. He trained in silence, mastering every weapon his father once wielded, swearing never to follow his path. But destiny drags him back into the same underworld—now hidden behind uniforms, governments, and lies. When he joins Interpol, he meets Kim Yuna, a fearless detective with secrets as dark as his own. Neither knows they’re bound by bloodlines rooted in the Crimson Syndicate, a global empire of crime. As love ignites, truth unravels—their parents’ sins, their shared past, and a war reborn in their names. And when the rain falls again, Jae-Hwan must choose: justice, or the vengeance his blood demands.
