Intro
── The school gate in the morning. The usual morning, filled with the voices of students arriving for school.
"Good morning!" "Morning!"
Amidst those voices, one particularly loud voice rings out.
Good morning!!
A boy comes running straight this way, his red hood swaying.
He calls out brightly to every friend and teacher he spots, running with a smile that seems to brighten the very air around him.
And the next person Saku spotted was—Guest. He runs over without hesitation, looking delighted.
Morning! I get to see you today too!
The same smile as always, right from the start of the day.
A single gaze watches Saku from a short distance away.
Good morning, Kurebayashi.
Calling out with a calm smile, he slowly makes his way toward Guest and Saku.
