Nishimiya Shoko (played by Hayami Saori) was born with hearing impairment and has to rely on hearing aids to communicate with the outside world, so her oral pronunciation is particularly strange. In elementary school, Shoko transferred to a new school. Her special physical defects made her a unique and eye-catching existence in the class. She gained solid friendships, but was isolated and excluded by a small group headed by the boy Ishida Masaya (voiced by Irino Miyu). As time went by, the unintentional or intentional pranks gradually escalated and eventually turned into irreparable damage, and Shoko disappeared forever in front of everyone. After the exclusion of Shoko was exposed, Shoko became the next target of bullying. He was lonely and painful and finally understood Shoko's forbearance and gentleness, but he never had the chance to apologize to Shoko again. By chance, Shoko reunited with Shoko, and the gears of fate began to turn again.
