Thanks to the black cat Gi with his magical powers, Midori has been reincarnated to a Princess Esmeralda in a parallel universe... but in the middle of her life! For some reason, the maids seem terrified of her and her fianc?, King Cyril, seems to hate her. Feeling sorry for Midori, Gi gives her the ability to morph into a cat... but the moment she became a cat, Cyril did a total 180! He's so loving and affectionate to cat Midori, but he can't hide his disdain for human Midori/Esmeralda. Now she has no choice but to do the best she can with what she's got! As he sees Midori put her all into everything, something changes in Cyril, too...
