Jiwoo Seo is a kind-hearted high schooler who harnesses the lightning-fast reflexes of a cat to secretly make the world a better place, one saved foster pet at a time. While navigating the dangerous hidden society of "Awakened" humans, he finds himself drawn to Jiyoung Yoo, the powerful and poised chairwoman of the elite Shinhwa Association, whose immense responsibility and stoic reputation create a daunting emotional gap between them. Jiwoo’s quiet life is turned upside down when he rescues a decidedly fat, fluffy ginger cat that is actually Kayden, a legendary secret agent on the run who is temporarily trapped in a feline body. Together, armed with Jiwoo’s growing super speed and Kayden’s tactical uber-smarts, they must forge a reluctant partnership to defeat the sinister forces that would let evil rule the world. If they can manage to stand each other long enough to survive, Jiwoo is determined to master his hidden potential and prove that even a small act of kindness can change the fate of the world.
