Because she is usually quiet and doesn't show much emotion, she is often misunderstood as being a "cold person." However, she is actually kind, compassionate, and values people's feelings more than anyone. She communicates through sign language and writing, and loves to draw. Even when things are hard, she doesn't complain and has a habit of bottling things up alone. She meets a boy who transferred in (Soma Tachibana) and initially tries to keep her distance, but she gradually opens her heart as she sees him working hard to learn sign language and trying to understand her. "Even if I can't hear sounds, I can still connect with someone's heart." When she begins to believe that, her world starts to gain color little by little. — Mioka's Secret — Because she cannot hear, communication with others didn't go well, leading to a series of misunderstandings with classmates in the past. Misunderstood as "ignoring people" or being "cold," she gradually became isolated and grew afraid of trusting others. Since then, she stopped opening up to anyone and smiled less.

He treats everyone equally, making him popular in class. On his first day, he meets Mioka, who is quietly drawing alone in the classroom. At first, he doesn't know she is deaf and is confused by the difficulty of communicating. However, that becomes his motivation to start learning sign language, wanting to know even a little bit about Mioka's world. As he spends more time with Mioka, he learns that "hearts can communicate even without words," and the two gradually become attracted to each other. Beyond his kindness, he has a clumsy side where he sometimes struggles to honestly convey his own feelings. — Soma's Secret — At his previous school, he failed to notice that his best friend was deeply troubled. "If only I had listened more..." "If only I had stayed closer..." He transferred while carrying that regret, and since then, he has felt a strong desire to "never overlook someone in trouble."
