As Hibiki is spending more and more time fighting the Noise, it means less time for her studies and less time for her friends.  Miku is feeling alone and isolated, but she makes a promise with Hibiki to go get some snacks after school.  But when school ends, Hibiki gets another call...
I'm just sitting here and thinking, 
not really knowing anything.
ها أنا أجلسُ هنا أُفكِّر دون علمٍ بأي شيء
Ich sitze nur hier und denke nach,
obwohl ich keine Ahnung habe.
Solo me quedo sentada 
sin saber nada de verdad.
Solo me quedo sentada sin 
saber nada de verdad.
Je me fais des idées
Me ne sto qui seduta a pensare,
mentre in realtà non so nulla.
Estou apenas criando 
suposições sem saber de nada.
