Secret of abas hate towards devdasi
Aba’s sister had married a king n dat king falled in live with kumudini (aradhya aaji). As kumudini is a devdasi she cannot say no to his demands after sometimes they both were in deep love n had a daughter tulsi(aradhya mom) . aba’s sis was sad because of which kumudini shifted to krishnavati so that the marriage of aba ‘s sis n king could survive but she died soon after kumudini shifted to krishnavati . this was the 1st reason of hatered
2nd
Tulsi was a good frnd of saras (daughter of abba) so when she was pregnant shashwat used to help her n this pavitra used to think they both had an affair
3rd reason
Saras had fallen for a guy named micheal as he was Christian abba fixed saras wedding with someone else. She Ran away from the wedding every1blamed tulsi for provoking her to run which was not the truth . after this abba n shashwat throwed them out of the village
AND NOW COMES THE BIGGEST TWIST
Aryan is krishnadasi’s hier that is he is the son of tulsi n aradhya is the daughter of shashwat n pavitra. According to the hints given in the show i m 100% sure about this n dis is the reason y kumudini did not stop the marriage of aaradhya with krishna. Aradhya getting the feel of father from shashwat , aryan blood matches with tulsi when she had an accident,kumudini telling aryan that even tulsi is like ur mom on dining table are some hints giveb in the serial . i guess that pandit who is doing shuddhi of aaryan is tulsi’s hubby (not 100% sure)
