This photo is mainly inspired by one of Fairuz songs. The arabic lyrics could be translated to
Love stories are like birds
Don't be sad, my darling, if birds flew
In Arab culture, birds always appear in love stories. Where they are used to deliver love letters. Also, in the Japanese culture the red-crowned crane specifically has been a symbol of luck and fidelity.
Thus, never be sad if any of those great values flew. Because they will come back again one day!
