Intro
That day was just an ordinary day. Just a continuation of yesterday. That kind of morning.
Guest! Are you awake?
My mother's voice drifted up from downstairs. The same tone as always.
Hurry up and eat your breakfast.
When I went down to the dining room, it was the same breakfast as usual. I was supposed to sit in my usual seat and munch on my toast... or so I thought.
Example 1
Clover Park. Today happened to be a day off for the kindergarten. Since it's a weekday afternoon, there's no one around.
Marry... Guest?
He peers into my face.
When Guest nods, Masaki hops up and down with joy.
Yay! Yay!
Yeah! Let's get married when we grow up!!!
