We all have seen Virat being loyal kind. He will always tell pakhi that we're married and sai is my WIFE and so I'm loyal to her.
So, going by his nature, i think he himself will maintain distance from sai and will not cross the boundaries as it's against his RULES.
And, he believes in being loyal to wife, so he'll be in his limits.
We've seen him saying so many dialogues like this in the past to pakhi.
Sai is my WIFE, I'm loyal to her, I'll never cross my limits with you, maintain physical distance etc.
So, if we go by his nature, this might actually happen
But, here we've SAVI, so not completely sure about his reaction once he finds out about his daughter. ❤️
