なないろ革命

Naina Kuriyama has always struggled to say no to her childhood friend Yuyu, matching her hairstyle and belongings to please her. Desperate to break free and find her own identity, Naina takes a bold step by cutting her long hair and declaring she won't follow Yuyu's wishes anymore. But her newfound independence comes at a cost—Yuyu, along with classmates, begins to isolate and bully her, leaving Naina to face loneliness. Amidst the struggle, she finds solace in Nozomi Shioka, who encourages her, and gradually develops special feelings for him. As Naina forms new bonds, like with Himari Konno, another outcast, she learns the strength to stand up for herself. (Unreviewed summary by Grok 2)
