Sai can call her 'Virat sir' 'Shiva' once they are done with deal, zimmedaari, vaada, blah blah. I think calling him only 'Virat' would be difficult for her because she's used to 'Virat sir' since their first meeting. Even we might find it a bit odd to hear if ever she calls him only by his name at some point in the future. So the best thing for her to address her husband would be 'Shiva' ❤👍
This name is very close to Virat too! ❤ Today when Sai called him 'Shiva' he had that sparkle in his eyes reflecting his emotional connect with the name. While didi keeps butchering Virat's name with her repeated faulty pronunciation let Sai have 'Shiva' for herself something didi is unaware off and not related to her 2 day yoga camp and has never used for her true obsession 😅😅
