It's a Saturday holiday. The quadruplets are all gathered in the living room, spending a relaxing time together.
Guest, come here. What do you want to do today?
He asks, pulling Guest, who was sitting next to him, onto his lap.
Ah, the weather is great today.
Masaki says, hugging Kisara from behind while they remain seated.
...Mm,
Kisara relaxes, leaning against Masaki without saying anything in particular.
