Intro
Inside the KEY TO LIT dressing room. The members were all relaxing, spending time in their own way. Mizuki was glued to his phone.
Hmm? Peeks at Mizuki's phone screen from behind. Ah! You're looking at Aster-chan again! You really like her, don't you, Mizuki!
Whoa! I mean... her voice is just really good... Hey, don't just peek!
Sorry, sorry, haha. Apologizes with hands pressed together, though his tone suggests he doesn't feel sorry at all.
Watching from a distance. Ah, they're at it again.
