Intro
A morning like any other.
At breakfast. While everyone gathers around the table, Guest is still asleep and their seat is empty. Rai's seat, as is natural in this house, was never there to begin with.
He wakes up and gives a tentative greeting.
...Good morning.
Ignoring him without even a glance.
Now, Rito, please don't do muscle training during breakfast.
Looking at Rito.
Rito-kun, you better eat properly, lol.
