A livestream prank sends a fearless myth-buster straight into another world—as the empire's disgraced, plus-size illegitimate daughter. Forced to marry the Crown Prince, she steals one unforgettable night with him before disappearing without a trace. Five years later, she's built a new life as a brilliant healer... and secretly raising his three children. Now the prince has finally found the runaway wife who was never supposed to escape.

Crown Prince Elias of Orlandia walks toward the wedding chamber, accompanied by his trusted confidant, Lorenz. Lorenz warns him that his arch-rival, Duke Selden, sent an obese illegitimate daughter as a bride to publicly humiliate him and provoke a breakdown. Plagued by old battle wounds and haunting trauma, Elias refuses his medication, swearing to avenge this insult himself. However, when he bursts into the bridal chamber, he finds the bed empty and is ambushed by Seraphina, who knocks him unconscious from the shadows. Gazing down at the fallen Blade of the Empire, Seraphina whispers a mocking taunt.

In this episode, Seraphina Lane, desperate for survival, boldly ties the unconscious Crown Prince Elias to the bed. She steals his royal badge as a pass to escape the palace. When Elias awakens and threatens her with fury, Seraphina flips the script; despite the looming death sentence she faces, she brazenly taunts and humiliates the notorious yet strikingly handsome prince at close range. Their relationship crackles with both volatile hostility and intense, ambiguous tension amidst this kidnapping and defiant teasing.

In this episode, Seraphina Lane discovers Crown Prince Elias unconscious and critically wounded, suffering from a deadly poison. Trapped in a nightmare, Elias relives the harrowing ambush from ten years ago. Upon checking his pulse, Seraphina realizes he has been struck by a potent neurotoxin. Deciding that since she has already benefited from the situation, she might as well help, she employs her family’s secret Divine Needle technique, using royal silver needles to draw out the poison. As Elias expels the black blood, his life is temporarily saved. With dawn approaching, Seraphina leaves one final needle to stabilize his heart and flees to avoid exposing her identity. Shortly after, the guards burst into the room to find Elias awake. Mistakenly believing the mysterious woman harbors hostile intentions toward him, a furious Elias orders a city-wide lockdown, swearing to hunt her down and make her pay.

In this episode, Crown Princess Seraphina Lane, now living under the alias Selena, attempts to escape the capital city of Orendia while being hunted by the entire city. Crown Prince Elias has ordered the city gates sealed, issuing a bounty for a skilled healer described as a "plump woman" who carries silver needles. Seraphina manages to incapacitate Elias with her medical skills and seizes the chance to flee. However, shortly after reaching the wilderness, she finds herself in a desperate situation after losing her belongings, only to be confronted by two robbers—one thin and one stout. Though Seraphina uses her superior combat skills to subdue the thin robber, she is caught off guard and knocked unconscious by the leader hiding behind her. Now, the noble princess has become a "prize catch" for the bandits, and her whereabouts remain unknown.

In this episode, a kidnapped Seraphina reveals her astonishing strength, easily breaking free from her restraints and overpowering her captors. During the confrontation, the bandits disclose their tragic backstory: a devastating plague has swept across the land. While the greedy Count Latin abandoned his people and fled with their wealth, the benevolent Count Gabriel exhausted his fortune to aid the poor, yet still could not prevent the ensuing famine. Just then, news arrives that Gabriel has also contracted the plague and is pleading for death. Seraphina reveals her identity as a doctor and resolves to set out to save the righteous nobleman.

At Blackraven Castle, Lord Gabriel is suffering from a deadly plague. To prevent the contagion from spreading to his people, he prepares to sacrifice himself and leave the castle. At this critical moment, Seraphina—who was brought to the castle as a captive under the alias Selena—intervenes to stop him. She instantly recognizes that the plague is not incurable and reveals her heritage as a descendant of imperial physicians from a great Eastern nation, possessing the legendary ancestral skill of the Ghost Hands and Divine Needles. Although Gabriel is deeply skeptical of such unheard-of Eastern medicine, he is eventually persuaded and compelled by his soldiers to submit. Under immense pressure, Seraphina prepares to perform the life-saving acupuncture treatment.

In this episode, Seraphina uses her exceptional medical skills to cure the plague affecting Gabriel, the leader of Black Raven Fortress, and his men, earning her the title of Saint. To escape the pursuit of her nominal husband, Crown Prince Elias, she decides to remain in the fortress, taking advantage of its strategic and treacherous terrain. Meanwhile, at the royal palace, Elias faces a political onslaught from Duke Zelden, who attempts to strip him of his title by citing his phantom pains and erratic, violent behavior. Realizing that the acupuncture treatment Seraphina provided that night was indeed effective, Elias issues a city-wide bounty, determined to track down the woman who holds the key to his fate.

Duke Zelden and his mistress Victoria plot to completely ruin Crown Prince Elias, mocking him for becoming the laughingstock of the nobility after offering a 500-gold reward to find his runaway fat princess. Meanwhile, outside the city at the Holy Light Fortress, Seraphina—now going by the name Selena—has gained widespread fame for her exceptional medical skills and beauty remedies, attracting countless lords. Elias sends messengers with 500 gold coins to seek her treatment, but Seraphina, terrified that her identity will be exposed, flatly refuses. However, in the ensuing struggle, Seraphina is shocked to discover that she is pregnant with Elias's child.

Six years ago, Seraphina Lane endured a grueling childbirth at St. Light Castle, welcoming triplets—two boys and a girl. Now, six years later, Samuel and Julian seize the chance while their mother is working out to sneak into her study. Their goal is to find a map of St. Light Castle and embark on a mission to track down their father, Elias, whom they have never met. Just as they think they have secured the map, they realize they have fallen into a trap set by their mother. A transformed Seraphina, now even more elegant and fit, appears on the scene to catch her mischievous sons red-handed.
