Princess Tishiena of the Salsiccia Kingdom was cursed at birth by a witch, leaving her with an endless hunger that no amount of food can satisfy. No matter how much she eats, her stomach never feels full. This insatiable appetite has been draining the royal treasury year after year, as the cost of feeding her grows increasingly unsustainable. Alfiass, a prince from a fallen kingdom who now serves as Tishiena's captain of the guard, works tirelessly to keep the kingdom afloat—haggling for cheap bulk ingredients, devising filling recipes that use minimal resources, and cutting every corner he can find. Despite his efforts, the financial burden of the princess's curse continues to mount.

Believing there is no hope of breaking the curse, Tishiena decides to take matters into her own hands. She resolves to secure her kingdom's future by proposing a political marriage to the wealthy prince of a neighboring country, hoping his fortune can cover her never-ending food bills. However, her plan sets off a chain of unexpected events. The neighboring prince, Colfitz, arrives at court but soon reveals a hidden and dangerous nature, putting Tishiena in a precarious position.

Meanwhile, Tishiena's relationship with Alfiass grows more complicated. After Alfiass shares a kiss with her, she begins to see him in a new light, and her feelings become harder to ignore. Yet Alfiass himself becomes entangled in a marriage proposal of his own, forcing Tishiena to confront the possibility of moving forward without relying on him. Determined to take control of her own fate, she resolves to find a way to break the curse on her own terms.

The story deepens when the witch who originally cast the curse reappears before Tishiena and Alfiass, hinting at the true origins of the magic that binds her. As the narrative unfolds, the search for a cure, the strain on the kingdom, and the growing romantic tension between the princess and her loyal guard captain converge in a tale of fantasy, comedy, and romance.
