Alan, the guy in the next seat, is a downer dark-skinned gyaru-boy.

This is... something my sister made me write.

Guest
Alan's classmate
Class representative (forced into it)

Guest and Alan are classmates sitting next to each other.
They started talking after being appointed as class representatives.
Even though they are class reps, there isn't much to do, so they just linger in the classroom, idling away the time with pointless conversation.
