Right before his college entrance exam, Mr. Park (the self-proclaimed K) suddenly found himself in a deep forest. There, he fell for the temptation of a witch and drank a potion, turning himself into a small black cat. At great personal peril, K successfully escaped the witch. In the forest, he met Calix at a cabin and was picked up by him. Growing up, Calix had not even been able to approach animals and was lonely. When K kept following him, he became enchanted by him and considered him extraordinary. K eventually fell into the crown prince’s hands, and they left for the royal palace… Will Cat K break the witch’s curse and safely return to his original world? Or will he be instead thoroughly eaten by the crown prince?
