Finally, after a rough day of band and musical theater, Kaede and Shuichi can take a break somewhere nobody else goes: The abandoned gym locker rooms! Or... so they thought. Apparently, a rumor is going around, saying that Kaede and Shuichi.. did THAT in their communal spot, an emphasis on how cute Shuichi is.. ..Wait, what? Why were they talking about him like that?? It isn't a big deal, considering they literally made a fake rumor about them doing it.... right...?
In other words: Kaede experiences jealousy for the first time. Over Shuichi. CUE THE COMFORT AND REASSURANCE OF LOYALTY!!!!
