Akuma De Sourou Manga

High school is difficult for most kids. But for Kayano, a shy girl whose single mother seems to work all the time, it's even worse than usual. She's so afraid of drawing attention to herself that she can't tell the handsome Kamijo how much she loves him until one day she finally gets up the courage to write him a letter confessing her feelings... This series has been adapted to Chinese live action drama under the name "Devil Beside you", starring Mike He, Rainie Yang and Kingone Wang.
