Cardbocchi can't shake the feeling he's being watched. One day, on his way home, he feels like he's being followed, so he runs...straight into a group of delinquents! Meanwhile, Haruo is looking for new choir members. Again.
But singing, I mean... 
I only know the songs my mom sang.
لكنّي... لا أعرف إلّا الأغاني
التي غنّتها لي أمّي
Ich kenn aber nur Lieder,
die meine Mutter gesungen hat.
Je connais aucune chanson…
Però io conosco solo le canzoni che cantava mia madre.
Насчёт этого... я знаю только песни, 
которые пела мне мама.
