"The world is cruel."

It's July 19th, and summer break starts tomorrow. Bocchi has... not become friends with her entire class. So she needs to make one more friend today, even if it's only one...
Am I the only one singing?
هل سأغنّي وحدي؟
Also singe nur ich?
¿Solo cantaré yo?
¿Solo voy a cantar yo?
Y a que moi qui chante ?
Quindi canto solo io?
Então só eu vou cantar?
Только я петь буду?..
