Ventafocs, the sole daughter of a wealthy duke, faced upheaval after her mother's early death when her father remarried and then departed on a long business trip abroad. Her stepmother and stepsisters immediately seized her room, forcing her into the attic, dressing her in servant rags, and burdening her with endless chores. Cherished keepsakes from her mother, including a dress later worn to the royal ball, remained vital treasures.

Possessing caramel brown hair, dark blue eyes, cherry red lips, and fair skin, she was consistently recognized as the most beautiful girl in the Emerald Kingdom. Her personality radiated profound kindness, gentleness, patience, and optimism despite relentless abuse, extending deep compassion to animals. These household pets—a dog named Patch, mice Chuchu and Bingo, and a bird called Pappy—gained speech through her fairy godmother Paulette, becoming her emotional support and helpers with chores. She aspired to live in a castle, own a horse, and gain many friends.

Her initial encounters with a mysterious boy named Charles involved friction due to his habitual lies about his identity, earning him the nickname "Charles the Fibber" and her early distrust. Shared misadventures—clearing false accusations of grape theft at the royal vineyard and aiding a distressed violinist—fostered mutual affection, though she lost interest in uncovering his truth after the vineyard. Romantic feelings emerged as an idealized admiration for Prince Charles, distinct from "Charles the commoner." This duality resolved into authentic affection for the boy beneath the deception, turning to heartbreak upon discovering his true royal status. Fearful of societal barriers, she withdrew from their friendship.

Prevented from attending the royal ball by her stepfamily—who mocked her mother's dress as outdated and destroyed her invitation—she received magical intervention from her fairy godmother Paulette. Attired incognito, she attended but fled at midnight, losing a glass slipper. A kingdom-wide search confirmed her identity with the matching slipper.

She actively participated in thwarting Duke Zaral’s coup against the crown. On her wedding day, Zaral poisoned the prince and kidnapped her, leading to a confrontation atop the castle clock tower. Charles intervened, defeating Zaral and restoring peace before their marriage concluded her journey.

Her character evolved from initial tsundere defensiveness toward Charles into warm friendship and love, growing resilient through wrongful accusations, magical mishaps shrinking her, and dangerous encounters with bandits and antagonists. Her optimism and ethics remained unwavering. Her stepfamily displayed fleeting remorse followed by renewed abuse, though a forced reconciliation came after her royal engagement. Fairy godmother Paulette operated discreetly, often disguised, providing aid long before the ball, honoring a promise to Ventafocs’s deceased mother.
