my guess is:
nw its shiela's tym to act a drama against rohan, she will act like she couldn't forget him and dearly loves him, rohan who believes in these gets married to her, then gradually shiela seperates rohan and his family from kajir and then takes revenge on them later with the help of saritha
in the mean tym, shiela who ends up in viki's house would help saritha to discover her love for viki.
i guess the story takes this path if its wrong i;m sorry😛
