In short, you're at school. The teacher was pairing everyone to their dorms, and now it was your turn. You've been paired with Byakuya, Nagito and Kokichi. When you enter the assigned dorm, you see the three boys. Byakuya reading on his bed and Nagito talking to Kokichi.

Byakuya: "..."

Nagito: "You should start going through the path of hope, Oma-kun!"

Kokichi: "Nah. Lies are better!" He giggles.
