Determined to escape this predetermined fate, he abandons his indolent ways and throws himself into a grueling three months of training in swordsmanship and magic.

Just as he begins to transform himself, he receives a surprising proposal for an arranged marriage to Letizia, a noble lady known throughout the kingdom for her own wicked reputation as a villainess who was recently cast aside by her fiancé. Expecting to meet a conniving and malicious woman, Alban is shocked to discover that Letizia is in fact a pure-hearted and gentle girl, exactly his type, who has been the victim of slanderous rumors and a sinister plot.

Realizing that his new wife is innocent and has been framed, Alban abandons his initial goal of simply avoiding his own ruin.

Their shared quest transforms them into the most formidable and terrifying married couple in the realm, as they fight to protect each other and rewrite the story's original script.
