Kono Monogatari wo Kimi ni Sasagu

"Please Let me be your editor, Hiiragi-senpai" One day, a high school girl, Natsume Kotoha, a self-proclaimed editor, appears before Hiiragi Yuuto, a lethargic high school boy. She follows Yuuto around asking him to write novels. No matter how many times he refuses, she never gives up. ...Don't tell me she know? That I was once a professional novelist who was hailed by the world as a genius. To escape that past, I had come to a rural high school where no one know. A former genius novelist who broke his brush and a high school girl who is an editor with a "Big Secret" weave a moving and inevitable coming-of-age story. (Source: Kodansha Ranobe Bunko, translated)
