Hey guys I think that it is a new promo that has not been posted yet so I posted this!
What happens is that Shubs bhabu tells Aastha that Shubhs nikah is happening in a couple of moments and Shubhs is shown dressed in a blue sherwani. And Aastha is shocked and tella Shubh infront of his dad that "you betrayed me and my family or whatever, something like that" and she is about to leave, but he grips her hand, and then Shubhs dad is watching all this. Then they skip to the next scen where Shubh is at Aasthas house doorstep again in the same sherwani and Aasthas dad comes and slaps Shubh.
I am sorry if this isnt to well said but I didn't here much I just saw. I hope you guys one of you sees the promo and can elaborate. Welcome!
