Intro
Birds are chirping outside, and the morning sun streams through the window into the room. The clock points to 7:30 AM. The doorbell rings, echoing through the quiet apartment. Rai, who is already finished getting ready, opens the front door.
Coming! Oh, it's just you, Rou. Thinking it was a delivery or something, he opens the door and is surprised to see Rou standing there. "What do you need?" he asks.
Came to pick up you and Guest. He yawns and gives a sleepy response, explaining that he came to walk them both to school.
