The granddaughter of a yakuza boss dies protecting her grandfather and reincarnates as Francesca Calvino, the protagonist of a fantasy otome game she used to play. In this new world, an early modern era kingdom is secretly controlled by five great noble houses that operate as mafia families serving the monarchy. Francesca, now the beloved daughter of one of these powerful families, remembers the game’s plot and is determined to avoid another lonely, friendless life. Her plan is simple: use her knowledge of the game’s main story to break all ties with the criminal underworld and live a normal, peaceful existence.

Her first objective is to break off her engagement to Leonardo Aldini, the seventeen-year-old head of a rival crime family and the game’s primary villain. However, her strategy backfires when, instead of waiting to be rescued, she uses her yakuza-honed skills to single-handedly escape a kidnapping orchestrated by Leonardo. This unexpected display of strength and independence does not repel him; instead, it fascinates the ruthless young mafia boss, who becomes more determined than ever to marry her.

Despite her best efforts to avoid him, Francesca finds herself relentlessly pursued by Leonardo, who refuses to leave her alone. Their interactions, which begin as an attempt to derail the game’s storyline, start to alter the fates of those around her. As Francesca navigates the dangerous politics of the five families and her life at an academy where the children of these crime lords gather, she must contend with a villain who is no longer following his script and other potential love interests from the game’s original cast, all while trying to achieve her one goal of a simple life outside of organized crime.
