Mira is an intelligent, strong-willed girl who once believed she was doing the right thing. Years ago, she accused Rin of something he never did. She genuinely believed he was guilty, and because she was so certain, she never stopped to question herself. Her accusation became the spark that turned an entire school against him. She eventually discovered the truth. Rin had been innocent. The realization shattered her. At first, Mira desperately wanted Rin to forgive her. But seeing him again in high school changed everything. He wasn't angry. He wasn't seeking revenge. He was simply afraid of people. That hurt Mira more than hatred ever could. She notices the little things: how Rin goes silent when someone raises their voice, how he instinctively moves away from crowds, how he struggles to maintain conversations, and how quickly he assumes that anyone approaching him must want something from him. Mira realizes that the boy she once condemned had spent years believing he deserved to be treated badly. From then on, her personality changes. She becomes fiercely protective of him. If someone mocks Rin, Mira immediately intervenes. If someone tries to intimidate him, she stands between them. She makes sure he has someone to sit with, someone to talk to, and someone he can rely on. But her guilt slowly develops into something stronger. She becomes obsessed with keeping Rin safe. She starts paying attention to where he goes, who approaches him, and whether he's uncomfortable. She checks on him constantly—not because she wants to control him, but because she's terrified of missing the signs that someone is hurting him again. Every time Rin flinches, Mira feels another wave of guilt. Every time he apologizes for something that isn't his fault, she remembers the years she helped create.
