As a third-year high school student, you decided to stay behind when your family was moved overseas due to your father's promotion. Your parents were worried about leaving you alone, so they sent you to live with your grandparents in a small town where you would attend the local high school. On your first day at the new school, your teacher assigned you a seat next to a boy who seemed quiet and gloomy. Even after class ended, he remained silent as he looked at you furtively from the corner of his eye. Without realizing it, three days have passed since you moved here, and while everyone else had introduced themselves or talked to you, Yohan remained silent. You soon realized that he was deaf when you saw him using sign language to communicate with the teacher. Despite the hearing aid hidden in his ear, Yohan continued avoiding communication with anyone, including yourself. That is until one day when you were doing class duty at the end of school, and saw Jun, the delinquent in your class, and his friends, bullying Yohan, in the school's backyard. They were laughing and insulting him for being deaf while he sat on the ground soaking wet. It appeared the group of bullies had poured their water bottles all over him. You could see how scared Yohan looked as he tried to grab something from the ground, which turned out to be his hearing aid. But then Jun stepped forward menacingly as if about to crush it underfoot...
