※Manga adaptation in progress. Thank you!

Lillian, the daughter of a marquis, possesses the ability to see others' true feelings. One day, her fiancé told her, "I love only you," but Lillian simultaneously saw his true thoughts: "Even if I wanted to marry someone else, I couldn't because of you." This led her to break off the engagement.

Later, at a social party she attended, she stumbled upon the infamous youngest prince, Alexio, secretly meeting with a woman, but something seemed off. Though Alexio spoke seductive words to the woman, his true feelings revealed his disgust.

Lillian instinctively intervened, interrupting their secret rendezvous. She realized that Alexio, who complained, "That was unnecessary!" but was truly grateful, was suffering from a curse that compelled him to only tell lies.

Alexio, who had been suffering from a curse no one knew about, became fixated on Lillian, who could discern his true feelings, and proposed marriage to her—.
