Synopsis:
For centuries, the so-called "Users" have been perfecting deadly techniques. Among them, the most feared clan is that of the "Poison Users ," one of the five most powerful families. Young Hikaru Gero carries this legacy in his blood. Living in the shadows and without any relationship with women, the concept of "marriage" has always seemed distant to him.
However, to prevent the lineage of the "Poison Users" from becoming extinct, the family patriarch decrees that his sister must forcibly produce an heir. At this moment, Hikaru crosses paths with Mei Shirosaki , a skilled con artist specializing in marriage fraud, who becomes his target.
To protect his sister and resolve the succession issue, Hikaru has an unexpected idea: to get married himself . So, in the heat of the moment, he asks Mei for help in his search for a husband.
