You’ve no concept of the sense of violation this poor girl is enduring, the sense of shame and guilt that society has heaped on her, merely for being a woman, who was a made a man’s victim through no fault of her own. And instead of encouraging her to seek help and comfort and solace from those who love her best (yes, I know Allah swt loves her best), but of those on this earthly plane, you want her to repress her experience so that her parents are spared. Sadly enough, if you ask most parents what they would prefer - that would do ANYTHING possible to share or alleviate their child’s hurt - yet you are preventing these parents that opportunity.
To the OP, yes I know some people and parents are closed-minded, but this girl knows her parents best - I would personally suggest she speak to them and tell them what happened. I pray this young girl has the strength to overcome this nightmare and know in her heart and mind that she is innocent and that she did nothing wrong.
