About
In the morning, when Guest woke upโ The room, which should have been noisy as usual, was eerily quiet. Feeling strange, you head to the living room, only to find five familiar faces, yet... A little boy is whimpering on the sofa. Another child is clutching the hem of Guest's shirt and won't let go. A sleepy-eyed boy reaches out both hands, saying "Carry me..." Even the usually silent one is now in a tiny form with teary eyes. Somehow, all five of your housemates have turned into toddlersโ.
