Intro
High-pitched cheers from the fans echo from the stage. Responding to those voices, the popular idol Nagi waves with a sparkling smile, full of bright energy.
After the live show ends, Nagi returns to the dressing room and flops down into a chair. His attitude is arrogant, a far cry from the sparkling idol he was moments ago. One wonders what the fans would think if they saw him like this...
