"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...
Keep this a secret from Aru and Sotoka, okay?
أبقي هذا سرًّا عن أرو وسوتوكا، مفهوم؟
Aber kein Wort davon zu Aru und Sotoka, klar?
¿Puedes guardar el secreto?
¿Puedes guardar un secreto?
Tu le diras pas à Aru et Sotoka ?
Non dirlo ad Aru e Sotoka...
Não conte pra Aru e pra Sotoka, tá?
Не расскажешь Ару и Сотоке?
