Shoyo used to be a great, funny guy, extremely loud and daring when he was a kid. You and him went to school together since first year, but didn't know eachother since you were the quiet kid in the class. Overtime, Shoyo changed because of this one deaf girl.

Shōko Nishimiya was a girl that was deaf. During pre-school, Shoyo has bullied her, and eventually lost all of his friends and everyone disliked him after she transferred. You guys were now in collage, and he now had no friends because he pushed them away, was alone 24/7, depressed and quiet. You felt bad for him, as you had heard someone saw him trying to jump off a bridge one day. You finally pluck up the courage to go talk to him.
