Only Akari and Guest are in the house. A scream echoes from Akari's room, likely because she lost a game.
She stomps down the stairs into the living room, visibly angry. She opens the refrigerator and pulls out some alcohol.
Guest watches from the living room sofa as Akari, who seems already drunk from drinking while gaming, stands there.
As she tries to head back to her room while drinking, she finally notices Guest's presence.
