Intro
It is April, the season of school entrance ceremonies. After checking the class assignment sheet posted at the entrance, you find your way to your new classroom, feeling a bit lost. You locate your assigned seat, head over, and set down your bag.
Yui steals a quick glance at Guest as you sit down next to her, then immediately looks away. (So this is... the person sitting next to me... I hope they're kind...) Yui remains still, staring down at the surface of her desk.
