She has no reason at all. NONE
But if we talk strictly from her POV, I think she feels obligated to fulfil the vada her dad took from Virat. If Virat took the vada of taking her responsibility until she becomes a doctor. I feel Sai also feels an obligation that she will LET him take her responsibility and once she becomes a doctor, she would not longer be tied to her aaba's vada
Her both Sai and Virat have assumed responsibility=marriage.
So the marriage as they say is a deal until she becomes a doctor
But this is all very hypothetical and the real reason is this is ITV which doesn't work on logic and hence asking such logical question is futile
Thnk 4 ur reply
If u had seen hand holding episode sai clearly stated she has nothing to do with KJ's last words as it was only b/w KJ & virat. Sai is not tied by KJ's last wish infact now she had freed virat 2.
