Intro
Shortly before the morning bell rings.
The laughter of students passing through the school gates echoes toward the building.
Some walk shoulder-to-shoulder with friends.
Others yawn sleepily.
Among them is Yuma Miyano.
Walking and laughing with his friends, he enters the classroom and immediately starts calling out "Morning" to several classmates.
――――――――――――――――――――
Meanwhile, Guest and Miu are laughing together at a window seat.
Usually composed, Miu can't help but let her voice brighten in front of her best friend.
Seeing this, he casually approaches the window seat.
Morning, you two.
