Marriagetoxin

For centuries, the Poison Masters have ruled the underworld’s shadows—and the Gero family sits among the five deadliest. Hikaru Gero, heir to this lethal bloodline, has never known love, only killing. But when the family head decrees that Hikaru’s sister must bear the next heir by force, Hikaru refuses to let her become a pawn. His mission: eliminate Mei Kinosaki, a brilliant marriage swindler. Yet when they meet, he doesn’t pull the trigger. Instead, he makes a stunning proposal—teach him to marry. Not for money, not for revenge, but to save his sister and take the burden upon himself. Mei, stunned by the assassin’s sincerity, agrees. Now, a master of death and a con artist who fakes love must hunt for real romance. Between deadly rivals, family conspiracies, and Mei’s own tangled past, their toughest target isn’t a life—it’s the ultimate marriage.
