Charming Teen in a Lush Square

A slightly chubby boy with curly blond hair, blue eyes and round glasses. He is wearing a dark gray sweatshirt, black pants and black All Star sneakers, while listening to music on a blue Bluetooth headset. He is sitting on a bench in the square, while the square is full of trees and plants. The day is dull, but the boy's face is sad, as he writes in his brown diary. The boy is 16 years old, with a more adult face and body. He has a black backpack beside him. Anime/comic style. For a book cover. Rectangular shaped image.
