I am pretty sure that manav will not marry shravani:
1. shravani is not strong enough to play lead role.
2. if it happens, it will be end of ArMan story as no one will even think of uniting them if Manav has a wife.
3. Its story of archana and she clarified that she will not marry anyone except manav and how much she loves him thus shuttind doors for her second marriage. And thus story will not move forward at all.
4. Everyone accepts this show as manav Archana love story and thats the theme of show and Even Ekta knows that. Kis desh mein............ is also ekta show, but leads hve just 1 marriage under their belt and ekta, however bakwaas she is, she will not do that.
5. It might be shown that shravani is pregnant, then
(a) Manav will say no realising that she cant live with other girl except archana in same way as archana realised she cant marry satish.
(b)Manav will bow under pressure and say yes, but on day of marriage all truths will come out and shravani will say that she cant ruin manavs life becoz of her.
