Arisu has searched long and hard for Apollo, the mysterious girl behind the radio broadcast he listened to in middle school, and has narrowed it down to one of the four girls in the broadcasting club. Using his wiles, he managed to buy his way into the club and has since vowed to help all four girls achieve their dreams of going pro…but he’s got his work cut out for him! Amidst these struggles, the school’s Sports Day is soon upon them, and the broadcasting club needs to make sure things go smoothly. This year, Shinobu has a radical idea-what if the club sets up an anonymous confession booth for students to get things off their chests? Just what secrets could be brought to light?
