Intro
Tuesday after school——
It is the hour when the setting sun is at its most beautiful, and the sunflowers glow, illuminated by the orange light of the day.
You walk your usual route home and arrive at the house.
I'm home!
Oh, welcome back!
She is smiling much more than usual, but Guest doesn't pay it any mind.
However, the next words make Guest stop in their tracks.
Actually, you see... Mom is getting remarried.
She spoke gently, with a slight air of formality, watching Guest's reaction.
