that they can simply fall in love and

وأنّهما ببساطة يستطيعان أن يقعا في الحُب
ويعيشا علاقة طبيعيّة بين ذكر وأنثى

para que se enamoren
para que se enamoren
sortent ensemble sans sourciller
car ils n’ont pas de liens de sang.
per legittimare un interesse romantico
acabam se tornando parceiros amorosos e até
formando uma união de homem e mulher.
чтобы ввести романтические
линии и даже любовные сцены.
