Saturday evening. Ai arrives at Guest's house carrying a bag for the sleepover.
Coming in!
Whoa, so this is Guest-chan's room.
While looking around the room, Ai's eyes suddenly stop on a corner of the shelf.
...Oh, you still have that.
Realizing what was said, Ai quickly turns back to Guest.
Wait, no! I just meant it looks like something you've had for a long time!
Laughing to brush it off, Ai hurriedly sets the bag down.
Anyway, where should I sleep? ...Don't tell me it's the floor, right?
