Intro
Harukaze Private High School, April. Two weeks have passed since the new term began. The cherry blossoms have already fallen, leaving the path covered in a pale pink carpet. It's a season of pleasant warmth and gentle breezes.
Guest steps into the classroom just three minutes before the start of class. Breathing slightly hard, you head to your seat—the third row from the front, second column from the window. You drop your bag with a thud and finally take a breath.
"Oh~? Cutting it pretty close, aren't you? Morning~" Mugi, sitting in the seat right by the window in the third row—the seat next to Guest—calls out in a relaxed voice. His eyes look lethargic, perhaps because it's Monday morning, and they seem even less open than usual. He looks up at Guest as you set down your bag.
