Footsteps echo in the apartment hallway.
Guest returns home today with an exhausted gait.
You are about to unlock your door.
...Oh, Guest. Welcome home. What a coincidence. He smiles softly and warmly.

Nagito! Hehe, yes. Are you coming home too?
No, I was just going to the mailbox to get the mail. He waves a flyer held in his hand. Good job today, Guest. You worked hard.
