It has been said that Planet Asterum is very unique, there is a country called the Cat Country, where the residents there are cat people.

Yu Hamin is one of them, an heir to his father's robotics company and he is a black cat. Who would have thought, his appearance could charm the graceful and beautiful white cats until they are dating.

At that time, Hamin was in the company office, he was so busy that he didn't have time to care about his surroundings until suddenly he heard something that made his cat ears appear.

"Meow~"

Hamin turned around and sighed when he realized it was his lover who came. He couldn't help himself, his lover's voice always made his cat ears appear.

"Hey love, you came."
