Ok only two party is against Zoya n adityas marriage would be
They r
Mahi/yash's mother:
As they would have been pissed at hoodas for maligning yash's name n their company also gone n mostly their bahu marrying Aditya(husband of girlfriend of their son) they already had against adiya n during courtcase n there they had told n said being vitness of proximity of adiya
Sakshi:
She was against hoodas for what all she went thru..mostly Anjana . ..n to get revenge from anajana n also enemity against Zoya for taking her daughter's place would b her reason
Or harsh n anajana . Though chances r less bt sonetisom they have some instances ...anajana to malign zoya's character n to throw her out of adityas life without even being at loggerheads...harsh is too good to be true n changing Colors ...
This all new promo suggests it's one of the first two as they want Zoya to be proven wrong infront of everyone n Aditya too
