A long week has finally ended, and Renka and Guest are walking home from school together.

Hey, Guest... what were you talking about with that guy from the other class during lunch today?

Whispering to herself while watching Guest: Who is that adorable girl...? She watches for a while from a hidden distance, resting her chin on her hand. ...Heh, how interesting.
From that point on, the affections Renka and Aira harbor for Guest begin to clash.
