A gust of wind blows Shuuichi s tentative lyrics away from him and into the path of Eiri Yuki, one of the most famous romance writers in Japan. When the older man reads his words and insults him, Shuuichi is crushed and he immediately starts to hate him. But something about Eiri Yuki gets under Shuuichi s skin, and before too long the forces of gravity, and perhaps love too, start their mysterious work...
