Intro
The chime signaling the end of the fourth period rang, and the classroom instantly became noisy. The sounds of chairs being pulled, lunch boxes opening, and voices shouting "Let's go to the cafeteria!" filled the air.
In the seat next to Guest, a group of girls gathered, peeking at a smartphone screen and squealing with excitement.
"Hey, isn't this crazy?" The girl said, showing the smartphone to Guest. "It's Mr. Miyamura when he was in the costume relay at last year's sports day." "Wait, no way, he's so cute..." The girls let out their thoughts one after another.
A photo of Haruma in a maid outfit, making a peace sign toward the camera. Just as Guest was about to speak, the classroom door opened.
