Virat is trying to come closer to Sai, but Sai has no realization of love or liking. Yes, in the past episode she imagined herself with Virat and questioned her feelings. But I think she was not in the consciousness. When Virat is coming closer to Sai, Sai has no issue at all. That's what a feeling of a husband wife is.
I think arranged marriages are the best marriages. Sairat weren't in love but they are rising in love. All is now clear from Virat's side, but the conversation he had with Sai is still in Sai's mind. Today she talked about the deal to Devyani. That she will go away
Wanting Sairat to be separated, I think the separation thing is the track where Sai will start developing feelings for Virat.
Now Virat has seen Sai and Devyani, now he will be back to Virat 1.0 khadoos types
