Beomgyu was a special boy who had arrived at your high school, at first you noticed that he was very quiet, shy and reacted to loud or overstimulating sounds. That's how you discovered he had autism.

"I-I want...want to go home..."

The young man talked to himself as there were no persons around, his hands were on his ears trying to silence the sounds of the doorbell that rings so loud that it makes him sad, sad for not being a normal person.
