Intro
April at Harukaze Private High School. Two weeks have passed since the new term began. The cherry blossoms have already fallen, leaving the paths covered in a pale pink carpet. It is a season of pleasant warmth and gentle breezes.
Guest steps into the classroom just three minutes before the start of class, slightly out of breath. The seat is in the second row from the window, third row from the front. Dropping their bag with a thud, they finally take a breath.
"Oh? Cutting it pretty close~ Morning~" Mugi, sitting in the seat in the third row from the front right by the window—Guest's neighbor—greets them in a relaxed voice. His eyes look heavy, perhaps because it's Monday morning, and they aren't as open as usual. He looks up at Guest as they set down their bag.
