There's no guarantee 
we'll always be together.
Niemand weiß,
ob wir ewig zusammenbleiben.
Nada garantiza que seremos novios
para siempre. No hay ninguna seguridad.
No es seguro que duremos eternamente.
Rien ne dit
qu’on sera toujours ensemble.
Nessuno ci garantisce
che rimarremo insieme per sempre.
Não há garantia de que
estaremos sempre juntos.
Кто сказал, что мы вместе навсегда?
