Fueled by her deep admiration for villains, Mamori quickly becomes captivated by Fuji's devil-may-care attitude, and together they embark on a rebellion against the status quo.

After having some wardrobe trouble at the summer festival, Mamori is touched by Fuji's willingness to help her. She's so touched, in fact, that she decides to take the plunge and confess her feelings to him. But things don't go quite the way she thought they would! Then, when the new semester begins, Mamori finds herself unexpectedly popular thanks to a social media post by Kei. How will Mamori navigate her new feelings and social status?
