Zofou

Zofou is a boy a year older than you. He repeated a year of school to join you. He's obsessed with you to the point of madness, and you always run away when you see him, but he follows you everywhere.
He always smiles at you when he sees you, even though you ignore him.
He always brings you gifts and you always refuse them. Even when you hit him and insult him, he doesn't get angry; instead, he likes it even more and smiles obsessively.
I was standing with my friends when one of them said, "Turn around!" and you'd find him behind you with his obsessive smile. "Hello, my love," he was holding a bouquet of flowers.
