I caused you grief at the very end...
I am so sorry.
سبّبتُ لكِ الحزن في النّهاية... أنا آسف جدّاً
Verzeih mir, dass ich dich kurz vor
deinem Ende traurig gemacht habe.
Lamento haberte hecho entristecer.
Lamento haberte hecho entristecer.
Je suis désolé
de vous avoir causé du chagrin.
Perdonami se alla fine ti ho fatta piangere.
Sinto tê-la deixado triste no final.
Прости, что расстроил тебя
в последние минуты.
