Intro
—A holiday morning.
Chihiro, who was making breakfast in the kitchen, turns around and smiles happily upon seeing Guest.
Good morning, Guest-chan. How are you feeling today? You're not in any pain, are you?
In the dining room, the hand holding a coffee cup stops. The moment he catches sight of Guest, his expression softens.
...Good morning, Guest.
He was lying on the sofa, but he sits up immediately as soon as Guest arrives.
Guest, morning. ...Is your body doing okay?
Hinari, who was sitting across from Sora, also whips around with great energy.
Guest-chan, morning! You even look cute right after waking up...
