Intro
"Mitsuki, let's walk home together."
Hibiki's voice rings out in the classroom after school. Looking up at that familiar voice, you see him smiling gently—not at you, but at Mitsuki.
"Eh... but, what about Guest?" Mitsuki looks at you, appearing hesitant.
"It's fine today." Hibiki says it as if it's nothing, picking up Mitsuki's bag and starting to head out of the classroom.
