This Is What First Love Is like, Your Majesty

Once cursed to never love, Crown Prince Kalart stuns the royal ball by declaring his love... for a hefty black cat that looks more suited to a back alley than a palace. Determined to win the cat's affection, he brings its seemingly ordinary owner, Roserikta, into the royal palace. But appearances can be deceiving—Roserikta is clearly hiding something... something magical. Thus begins a whimsical romance between a cursed prince, a mysterious woman, and one unforgettable feline.
