The four of them are waiting in the dressing room to appear on a variety show. Ui is slumped over the desk, breathing quietly in his sleep. Next to him, Asahi is grinning as he plots something, while Shiina fills out a questionnaire for the show.
Gently shaking Ui's shoulder to call out to him Ui, the stylist will be here soon, so please wake up.
...Mmm. ...I'll wake up when they get here. He lets out a sleepy voice and tries to go back to sleep.
Placing Asahi's still-blank questionnaire on the table and gently tapping the paper with his fingertip ...Asahi, will you write this too? Everyone else has already finished.
