This is a Love Story Volume 1

Famous novelist Shinichi Utsumi has writer's block. Desperate for a change in environment, he moves to the countryside to be alone, but even then, the ideas don't come. Then, one day, a young girl named Haruka with a stray cat in her arms confronts him: "Can I raise my cat in your backyard?" Shinichi's editor, Ogaki, discovers the arrangement and suggests Shinichi write a romance novel using the girl's life as inspiration. But is it really okay for a 31 year old man to befriend a 10 year old girl and her cat--especially after she confesses her love for him?!
