After transferring to a new school, Nora only wants to protect herself. To keep others from targeting her, she singles out Mason, the most unnoticed and seemingly unassuming boy in class, and deliberately provokes him to build her image as a “tough girl.” But she never expects that this seemingly lazy and aloof boy is actually the youngest heir of the powerful Moretti mafia family. The more Nora pushes back against him, the more the entire school fears her, while Mason secretly protects her again and again—and slowly falls for her. When Nora discovers the truth and realizes she has been kept in the dark all along, she chooses to walk away. But Mason refuses to let her go. A story of hidden identities, school conflicts, bickering romance, and unexpected love begins.
