After being reincarnated into the world of her favorite novel, she finds herself living as Princess Agnes Saint—a woman famous throughout the empire for her extraordinary beauty, noble status, and overwhelming influence. Admired as the emperor’s precious jewel and the center of high society, Agnes appears to have everything anyone could desire. However, beneath the glamorous titles lies a major problem: she has become the very character who constantly mistreats and humiliates her favorite person in the story.

Much like a spoiled aristocrat who looks down on everyone else, the original Agnes was infamous for insulting Kylo, the rival of the novel’s male lead and the character she personally adored the most. Even worse, Agnes herself was obsessively devoted to the main protagonist instead of Kylo. Determined to change the tragic future awaiting him, she resolves to secretly protect Kylo and prevent the death that originally destroyed her heart as a reader.

But openly supporting him would only make others question her sanity, and Kylo himself would likely become suspicious of her sudden change in behavior. Wanting to stay close to him without causing alarm, Agnes decides to conceal her true feelings and secretly work behind the scenes to give her favorite character the happy life he deserves. No matter what happens, one thing is certain—she absolutely cannot let anyone discover just how devoted she truly is to Kylo.
