The spectacle with Irene and her father concludes with the people in support of Elianna as the prince’s betrothed. Wanting to spend some private time with his fiancée, Prince Chris plans a special date at a traveling book market. Eli cannot contain her excitement, surrounded by books and with the man she loves. But soon their romantic outing is interrupted by an accusation and a child—a child claiming that Prince Chris is his father!

When book-loving Lady Elianna spots Prince Christopher—her betrothed in name only—consorting with another noble lady, she realizes the recent rumors must be true. The prince has someone he truly loves, which means the annulment of their engagement is both inevitable and fast-approaching. What she doesn’t realize is that this is merely a surface ripple—one of many where the truth runs deep, in a conspiracy surpassing her imagination!

Our Bibliophile Princess spent her days thinking her relationship with Crown Prince Christopher was merely a facade, but now Elianna knows their feelings are mutual. Unfortunately, not long after they confirm their love, His Highness has to leave for the Miseral Dukedom on official business. Elianna is left to attend the Autumn Hunting Festival as his proxy. She’s determined to live up to his expectations, but things don’t go to plan as she finds herself swept up in a brand new adventure!

Inept with a sword, unable to ride a horse, and apathetic toward the empire he serves, Regis Aurick is a hopeless soldier who spends his days buried in books. Banished to the borderlands, he encounters a stirring young woman with red hair and ruby eyes. She is Fourth Princess Marie Quatre Argentina de Belgaria, known simply to Regis as Altina. “…Do you want to become my tactician or not?” Having sought him for his rumored strategic prowess, she aspires to reform an empire led by self-seeking nobles and driven to pointless wars, the legendary blade of an emperor, the Grand Tonnerre Quatre, at her hip. Continuously underestimated by her regiment, including her would-be tactician, the princess resolves to prove her worth beyond a shadow of a doubt—no matter the risk. Here is a tale of war, love, and politics, woven by the bookworm and the sword princess.

Oh dear, it seems I was reincarnated into a modern otome game from a fantasy world! All I ever wanted was to be free of my responsibilities as a countess and I finally got my wish when I was reborn as a commoner in modern Japan. Everything was going perfect, except it turns out this is the world of an otome game and some crazy girl who goes around calling herself the “heroine” is upset at me for stealing all her “events” with the “love interests”… Now she wants me to team up with her against the “villainess”. I’m supposedly just a random NPC, so why am I being dragged into this?!

Our Bibliophile Princess spent her days thinking her relationship with Crown Prince Christopher was merely a facade, but now Elianna knows their feelings are mutual. She was serving as his proxy at the Autumn Hunting Festival, but then another noble lady locked her inside an old castle where she was then assailed by foreign rabble-rousers. Fortunately, the prince swooped in with a timely rescue, but just who coordinated this attack to begin with?! There are ulterior motives at play here—ones that seem to involve the entire country.

Elianna and Chris continue their investigation into her family history, only for treachery to strike at a book market!
