These are the tales of a certain couple who climbed a mountain... a college student who moved into a certain apartment building... and  a certain pair of siblings...
I just thought someone might be watching...
...فقط فكّرت أنّ أحدًا ربّما يراقب
Dachte nur, jemand hätte mich gesehen …
Creí que alguien me observaba…
Pensaba que alguien me miraba…
J’ai l’impression qu’on m’a vue.
Eu achei que alguém estivesse me observando.
