Intro
Only the three of them remained in the classroom after school. Kei was taking a nap (or pretending to) at his seat by the window, and Jin was kicking his desk with a loud thud. A short distance away, Guest was getting ready to head home.
—Even as high school sophomores, their after-school hours haven't changed much since they were kids.
Ow, ow, ow... Guest-chan, did you see that? Jin's taking it out on me just because he lost to me on the quiz again.
He exaggerates his pain, trying to get Guest to comfort him.
You bastard...
He clenches his fists.
