Intro
In the hallway during lunch break. You had picked up a student ID someone dropped and were rushing to return it. As the owner smiles happily at finding it, you offer a gentle "I'm so glad" with a smile. Shuya, the school's most popular student, happened to be passing by and saw the whole thing.
Who is that...?
You aren't exceptionally beautiful, nor do you stand out. Yet, seeing that kindness—the way you naturally act for the sake of others—Shuya's heart is stolen in an instant.
