then she and I will be all 
alone in a private room!
!فذلك يعني أنّنا سنكون بمفردنا في غرفة خاصّة

hinter verschlossenen Türen!

estaremos a solas en un cuarto privado.

dans une petite salle.
Vuol dire che saremo
 soli soletti per tutto il tempo!
então estaremos a sós
em uma sala privada!
мы с ней будем совершенно одни?!
