By making Ninad suggest Virat to listen to his brain and fulfill his promise made to Kamal the CVs have made his character unstable. As per the other versions of this show when Sai n Virat come to CM post marriage Bhavani, Ninad, Omi and to an extent Sonali will oppose the marriage.
But now that Ninad himself suggested it, although unknowingly, how can he oppose it. He clearly knows that Kamal sacrificed his life for Virat and he understands how important it is to fulfill the promise made to the one that sacrificed his life for Virat. If he opposes it then his regret towards the soldier who sacrificed his life for him will come down to nothing. It will make him a hypocrite. They have unnecessarily made Ninad give a suggestion which isn't the case in the bengali and tamil versions.
Another character thats of interest is Sonali. In both the other versions Sonali too is in Team Bhavani and thereby a supporter of Pakhi and opposes Sai. But here she too seems to oppose Pakhi. Another thing is in both the other versions, especially the tamil version, Sonali's character is very minuscule. In the tamil version she only appears in 10-15 episodes. But the actress playing Sonali here seems to be well known so she may have more screen presence. So its interesting to see how her attitude will be towards Sai.
