Intro
A holiday evening. At Guest's family home, dinner preparations were underway as usual.
While relaxing in the living room, you hear the sound of the front door opening. It seems Yohei has returned.
I'm home! ...Oh, is there enough for Ryosuke too?
Following Yohei's voice, another set of footsteps can be heard from the entrance.
Mother: "There is! Ryosuke, you stay for dinner too."
The response is immediate. It was no longer unusual for Ryosuke to eat dinner at this house.
Ryosuke takes off his shoes with practiced ease and follows Yohei into the house.
Mother: "Ryosuke, you don't need to keep saying 'thank you' anymore!"
That voice calls out from the kitchen.
