Maybe if u look at the business angle for zosh to get going Mahi has to cooperate, she is evil.. Adi realises this before zoya and tries to befriend her.. He is doing it for zoya..Mahi has gone bonkers abt adi as he saved her life.. ADI being adi, does things differently and apart from his brother no one understands him..eventually he is the one who will look after zosh and zoya but the way his character is being developed.. It really harms his intentions.
So as per spoilers zosh becomes successful, mahi is v much part of this success.
(If cvs bring in a character change in adi as someone who also is trying to be a business man and treats zoya with equal warmth.. It will be good to watch. Lets hope its going in that way. )
Mahi realises that it was Zoya that mattered to him will come back as a vamp..
Maybe the marriage track was a damage control promo so that we know its adiya all along... Otherwise as usual channel and cvs ke hathh mein hai sab kuch
