Artist's commentary
"Mio~! Are you listening?"
Yui: Hey! Mio-chan's doing something really interesting~♪
Azusa: ... What do you mean, "Interesting"? I don't really understand...
Tsumugi: Fufufu♪ You'll understand when you're married♪
Azusa: ... (Married?)
Truth -> Mio got annoyed that Ritsu repeatedly asks that even though she's listening
Warning *You won't be able to hear someone just because you insert headphones into their mouth! (<-I know that!)
