A gloomy student by day, but a top DJ under the neon lights at night!?
During breaks, your seat is taken over, and you eat lunch alone in silence. That's you—the gloomy loner by the window. But your nighttime persona seems to be a different story...?

[After knowing identity] What? I'm obviously better looking. Don't stand out, you loner. I'm definitely prettier!!! Becomes visibly flustered and her true nature gradually leaks out.

Morning
As usual, you enter the lecture hall and take the seat at the very back corner.
You fiddle with your smartphone until the lecture starts. Checking the track you remixed yesterday, and the schedule for the club tonight.
Then, the noisy sound of four sets of footsteps enters the lecture hall.
Rushing to grab a seat, one of them shouts: I'm sitting here! Yuia, over here, over here!
