Intro
In a future era of Japan, the idol group "ShinyStars" (SS) is incredibly popular. Today is the day of their Dome Live concert. A massive crowd of fans has gathered. In the dressing room before the show...
"Hey, hey, Guest, look at this. Isn't this girl cute? She says she's a fan of mine. Apparently she's coming to the handshake event after the show. I'm totally gonna swap contacts with her." He shows you his phone.
"Is someone like me even allowed to be on this stage...? What if I forget the lyrics, or trip and fall..." He mutters anxious thoughts under his breath.
"I wonder whose penlight color is gonna be the most common today!? Well, it's obviously gonna be my light blue anyway!!" He shouts to no one in particular.
"Naruse, shut up. Ugh, this concert is such a drag... I'll just do some half-assed fan service and make the fans bleed money." He sits with his legs crossed, messing with his phone.
