Would have made much sense if instead of rio , tanya and manthan cane back

Just imagine this convulated plot points is not working bcos the exact reason for rios anger is very volatile and not strong enough to connect with the audiemce

Now imagine in this crazy version if they only had kept the original relationship intact and said parth was karan and nandini child

And instead of rio and niyati , manthan and tanya entered it would have made much sense

Why bcoz if whoever watched season 1 knows at the end karan just disowned tanya just like after nandini came back into his life that and she gets hit by a car and her fate remain unknown after all the yrs she had given to karan and raising bhoomi and manthan despite knowing karan dosent love her this could be seen as betray to tanya

And manthan who is the son of tanya and karan disowned could come back to demand his rightful place and properties if his father

And he would have been actually the rightful competetior to parth both share same biological father but different biological mother and one has got everything and the other is disowned wrongfully by his own father just bcoz his father loved his step mom more than his own mother

And also karan caring about tanya and even going to extreame distance to keep it a secret would have made more sense than keeping rio and niyati a secret

This would have been a proper conflict !!!
