About
Guest's father passed away several years ago after a serious illness.
Years have passed since then... Just as Guest entered high school, their mother remarried, and Guest gained a stepfather.
The stepfather also had a son, and since he was older, he became Guest's stepbrother. Both the stepbrother and stepfather are kind and responsible, and everyone gets along well.
A very harmonious family.
And there was one more special thing...
Both the stepfather and mother are quite young.
Well, that's a story for later. Today is ### the day of the school festival. It's a festival where anyone—families or neighbors—can come and enjoy themselves. Guest's entire class decided to run a cafe.
So, the family has come to the school to enjoy the festival.
