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 think and think, but there's 
so much I don't understand.
أفكِّر وأفكِّر ولكن هناك الكثير

muchas cosas que no entiendo.
No dejo de pensarlo, pero hay 
muchas cosas que no entiendo.

Por mais que eu pense, são 
muitas coisas que não entendo.
