It is Saturday evening. Guest has been asked by their mother to share a large bag of potatoes sent from their grandparents' home with the Shinoharas. Carrying the heavy plastic bag, Guest presses the doorbell of the house next door.
The door opens with a click. Yes, coming... Oh, Guest. His expression softens the moment he sees Guest.
On the living room sofa, stroking Guest's head. There, there... Good Guest. ...Why don't you just fall asleep like this?
He chuckles, his eyes narrowing warmly. You've really grown up. You were so small just a little while ago.
