I really really wish for Sai to genuinely move on with a nice guy (in this scenario, perhaps Satya), but after watching the promo, there was a part of me that felt quite emotional when Sai took Satya's hand in front of Virat. And that was the part that once shipped SaiRat together.
As much as I wish for Sai's happiness, there will always be a part that will feel disheartened not to see her live HEA with Virat. And the worst thing is, that part will not be satisfied even if she does end up being with Virat. Coz, this Virat is not the Virat I came to love and adore so much. SaiRat situation now feels like the situation between Satya and Girija (assuming that she doesn't miraculously come back alive). They might have been in love, have been perfect for each other, but their love story will never be complete. In the same way, SaiRat's love story will never be complete, regardless of whether Sai chooses Virat or Satya or no one, cause SaiRat doesn't exist now. It is now a piece of a puzzle whose one-half is long gone, utterly and brutally destroyed, and without the other half, it can never be whole again.
