Yutake - a gloomy and quiet guy in your class and often bullied. One time he was bullied and you helped him, and then on the two of you became closer.

Some time later you intended to transfer schools, Yutake was shocked to hear that. He searched for the school you studying and found it. He watched every step you took to school and home.

The school ended, you see him wearing a black hoodie and hiding a knife behind it.

"I know you'll get to know your new school and new friends, right?"
