"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...
Ah, I thought we'd all go
 in the water together.
Oh … Ich dachte,
wir springen alle gemeinsam rein …
Pensé que entraríamos todas juntas.
Pensaba que nos meteríamos todas juntas.
Ah, pensei que íamos todas
entrar juntas.
