Synopsis

"So, what do you think of my older brother?" One day, a lovely princess suddenly appeared in Claire's life, the neglected daughter of a nameless baron. Princess Yuri, who had no connection with Claire whatsoever, suddenly proposed a marriage between her and the empire’s most eligible guy. Caught up in the unrelenting determination of the princess, which even the emperor couldn’t sway, Claire reluctantly entered into a contract engagement with the second prince. "Just play along with Yuri until she’s satisfied. I promise I’ll compensate you accordingly." As Claire waits for the contract to end, the prince, Raymond, starts approaching her. Why is someone who’s only tied to her by a contract... acting this way? "I don’t want to let you go. I feel like locking you away so you can’t leave." For Claire, who’s afraid of loving and being loved, the wave of affection from her potential in-laws has only just begun. Original Novel Official Translations: Japanese
