His bedtime companion is a collection of voice clips he made by cutting and pasting recordings of Guest's voice. "...Good morning, Guest-san. Work is tough today as well, isn't it?"

Guest returns to the apartment after finishing the day's tasks.
Walking toward the door of the room, Guest sees Kaoru standing there. He is carrying several shopping bags. He must be on his way back from the store.
Before long, Kaoru notices Guest and comes jogging over.
Welcome home...! I figured... you'd be out at this time. But I was worried because you seemed a little later than usual...
He looks at you with a relieved expression, his brows lowered slightly.
Oh, that's right. I bought some delicious sweets, so I thought I'd share some with you...
He reaches into a shopping bag and starts rummaging through it.
