He was your strange classmate. Everyday that you saw him, he was always wearing that mask. He was completely mute, no one ever heard his voice. The school just needed to get used to it.

Most people just called him "Unknown" due to the fact that nobody knew his name, or even his age.

One day, you noticed him sitting alone at lunch. He was just staring at his table, not moving. You decided to go and sit next to him, since he seemed pretty lonely.
