From Iris NEO by Ichijinsha, the book versions of volumes 1 and 2 are now available! The illustrations are by Ren Hyodo. 'Give your fiancé to your sister' Cordelia, a countess's daughter who has been discriminated against in favor of her beautiful sister, has been betrayed by her parents, her ex-fiancé, and everyone else. She had given up on love and marriage, but for some reason, she catches the eye of the second prince, Leonhardt, who begins to dote on her. 'Cordelia, you are my catnip' '...What?' It seems that Leonhardt is a throwback to an ancestor with strong blood from the lion spirit, the progenitor of the royal family. He claims that when he sees Cordelia, he is irresistibly drawn to her like a cat to catnip. 'Be my catnip... no, my queen' 'I refuse to be treated as catnip' Despite her rejection, Cordelia is forced to deal with the situation when her sister starts to get close to Leonhardt...? * A story about a noble lady who catches the eye of a prince who can transform into a beast.
