After being pushed to her death by a mysterious figure, Hanasaki Rinko reincarnates in the world of a novel as Raeliana McMillan, a side character destined to be poisoned by her fiancé.

Raeliana moves to the Wynknight mansion so she and Noah can be officially engaged. She used her knowledge of Noah's possession of the royal seal to convince him to make the deal with her, but Noah seems unfazed, making her wonder if he'll really accept.

Raeliana begins her bridal training at the Wynknight mansion. She and Noah must put on the perfect performance to convince society that their engagement is real, but the road ahead of them is clearly rocky...

Noah and Raeliana attend a ball. Raeliana attempts to get closer to the wife of Marquess Eriteal at Noah's request, hoping to make him owe her a favor, but then another character from the novel appears: the antagonist Vivian.

Raeliana has been kidnapped, and a rescue by Noah and his knights is her only hope. But can they make it in time? And what kind of trap will they find waiting for them if they do?

Raeliana wakes up in Noah's room, with Noah lying half-naked beside her. Panicked, she seeks Adam's help in fleeing the mansion. Noah sends out all his knights to find her, but Raeliana uses a maid disguise to avoid discovery.

Raeliana attends the annual monster hunt in the Sycret Mountains, where each lady traditionally gives a handkerchief to her chosen participant, who in turn gives the lady a monster he's killed. On the first day, Noah makes a request of Raeliana...

During a break in her purification period, Raeliana encounters His Holiness Heika, and their first meeting quickly devolves into an argument. But this only makes Heika more curious about the girl who spoke so impudently to him...

Heika tries everything he can think of to make Raeliana agree to be his disciple. He opens the seldom-opened gate to the Holy Land and summons its knights to show off his authority, and even tells Raeliana he'll be her grandpa.

A maid tells Raeliana about a mirror in the west building that promises to give visitors any information they want, and warns her not to go near it. But Raeliana is too curious about what could have happened to Beatrice, the novel's heroine...

Raeliana continues to wonder what's become of Beatrice. When Raeliana visits a place Beatrice visited in the novel's plot, she meets someone completely unexpected instead, and learns that the status of the royal seal has changed.
