I dont think we will see any scene where Sai is competing with P for V's affection.... that is a moot point...
Sai will be too upset and she is not a person to do this mera pati tera pati thing...
jab legally uska pati tha lekin deal main tha usne tab P se compete nahi kiya to ab kya karegi....???
Sai will initially have a heartbreak ofcourse, but she is a steely woman... she will just care for Saavi and atmost Vinu if she goes in CN...
Whereas V might expect her to do all this for him like earlier and she will deny...
Agar mera golden tongue hai to mujhe ye dekhna hai...
V squirming and wanting to be with Sai...
P not giving him space and is being obsessive over him... irritating him in the process...
CNwasis being very sweet to Sai and Saavi because Vinu likes them both.
Harini adding tadka to the fire
Sai being quiet and reticent in all this and simply watching the proceedings confusing everyone with her silent treatment.
