why is this so different from the novel? yohan never bully jun in the novel

its not actually different from the novel. jun was getting bullied in the novel too but later he finds out yohan wasn’t the one behind it. the manga will probably go in the same direction too

there is slightly different, yohan never throw the ball to jun in public, he throw it to jun because jun was talking to jaehyun which make him jealous
