I found out that one-sided 
love is very painful.
.اكتشفت أنّ الحب من طرف واحد مؤلم
Dass einseitige Liebe schmerzlich ist.
Me duele que no me corresponda…
Me duele que no me corresponda…
J’ai compris que l’amour
pouvait être dur…
Solo che gli amori 
a senso unico sono dolorosi.
Descobri que amor não correspondido
é muito doloroso...
Оказывается, любить без взаимности
очень грустно…
