Imouto ni Konyakusha wo Toraretara, Kemono na Ouji ni Kyuukon Saremashita: Matatabi toshite Dekiai saretemasu

Cordelia, daughter of a countess, can't seem to get married–mostly because her little sister Priscilla keeps stealing the hearts of her suitors. Ready to resign herself to a spinster fate, Cordelia is surprised when a handsome man suddenly courts her–and he's a prince, no less! Prince Leonhardt, who possesses the power of a legendary lion, is a widely admired man but has his own quirks, such as pursuing Cordelia because he was drawn to her scent. How cat-like is this man?! A fun (and feline) fantasy romance!
