Six-year-old Liliana Clarke awakens from a week-long fever with two shocking revelations: she remembers her past life in Japan, and she is the villainess of an otome game. Her joy at this knowledge is short-lived, however, as the illness has stripped her of her voice entirely, leaving her unable to speak. In a world where magic requires spoken incantations, this affliction—possibly a curse—makes her a crippled noble in a den of vipers. As the daughter of one of the kingdom’s most powerful political figures, Liliana is a prime target for assassins, and without the ability to call for help or defend herself, her situation seems hopeless.

The story is set in a fantasy kingdom torn apart by political intrigue, where a coup appears imminent and a mysterious, unnamed mage runs rampant sowing chaos for a hidden master. Despite her muteness, Liliana discovers a loophole in the magical system: the rules are not as ironclad as believed, and with sheer power of imagination, she can perform magic without a single word. This realization unlocks her latent potential, making her an overpowered force who can manipulate the world around her in almost any way she desires.

As the narrative unfolds, Liliana must navigate deadly assassination attempts and complex power struggles while pretending to be a harmless, voiceless child. Her primary goal is to avoid becoming the official fiancée to the crown prince, a position that traditionally seals the villainess’s doom. However, the prince has other plans and refuses to let her break off their engagement. She does find allies, including the talented mage Petra, who treats her with surprising informality, and the mercenary duo Gildo and Olga, who are amazed she is unlike other nobles. Conversely, her father provides one of the most chilling moments in her journey, murmuring with cold disappointment when he finds her still alive after a deadly monster stampede.

Notable arcs include Liliana’s fight to stop a rampaging monster stampede that destroys a town and kills dozens, an event that drains her mana and nearly kills her. By the end of the first major story arc, she successfully regains her voice. However, rather than revealing her recovery, she makes the calculated decision to continue feigning muteness. This allows her to observe her enemies from the shadows and maintain her strategic advantage as the mysterious antagonist, who is often seen eating an apple and is determined to wipe her out, continues to lurk in the background.
