My Roommate is a Cat

Novelist Mikazuki Subaru has no interest in anything but books and can't stand it when people interrupt his writing work. One day, by chance, he finds a stray cat and brings it home to live with him. As he watches the cat behave in ways he didn't expect, Subaru comes up with all kinds of ideas for his latest novel. He's pleasantly surprised that the cat doesn't interrupt his work and even stimulates his imagination... but then the cat starts scattering its food around, and scratching at the door to his room. Maybe this creature really is nothing but trouble?! But the cat has its own thoughts on the matter...
