Cheon-Jae, Man-Jae, Baek-Jae!

Siblings with personalities and tastes as different as night and day: Cheon-Jae and Man-Jae. Unlike Cheon-Jae, whose social skills are maxed out, Man-Jae's only friend is the youngest cat, Baek-Jae. “With no one to meet but books, I can't help but study well!” Cheon-Jae schemes to find Man-Jae a friend, while Baek-Jae watches it all with disdain... One cat, two humans. The chaotic and delightful daily life of three siblings! (Source: Naver, translated)
