At the risk of bringing offscreen...
NB Aish are getting double income... in leap scenario both will lose jobs unless they take a leap of 20+ years. Won't take that risk. For them it's better the story continues in this phase of toddler kids.
Don't think they will agree to play parents to young adult like Harini actress is either ...
Neither can play a 25+ adult physicality wise.
Ayesha is closer and can still play 25+ Saavi.... but that would need age defying too.
Moreover, if Sai doesn't get justice and dies for the story to take a leap... VP child against Saavi Vinu will hardly be watchable.
What's more irritating would be seeing NB as Vinu and Ayesha as Saavi... when SaiRat have not got a happy ending and they have awesome chemistry as romantic ship for what it's worth.
To see them play bro sis would be next level cringe!!!!!🤢🤢
I agree plus aria as Savi has been too popular
