Its simple yaar, acc. To me, the new guy shivam took her ofthe party and try to use her, par swayam le hote huwe aisa thodi ho sakta tha, he reached there nd saved her buthe was a bit late as the guy shivam had already hurt her... Then swayam fights with him, take sharon from there to her home nd then leave her alone and left... This is how sharon got hurt acc to me...
