Also for me this show is about how Zaid and MJ handle situations. If I go on about the morality of the characters believe me, I can't watch any show for that matter. Humans are grey. Yes, some are really positive, some grey and some are negative and criminals. But it's not really easy to divide people on that basis..lines blur.
Now, for me, I see this show as Zaid loved Ayra but since she didn't choose him, he married MJ in an impulse and treated her badly. Blackmailed and then married Ayra finally. Then he started liking MJ as well. Now, this story is about whose love lasts, Zaid-Ayra or Zaid-MJ. Now I judge this based on the dynamics between the couples. Ayra-Zaid don't seem compatible. She brings down his energy. Ayra might not be negative but she is selfish and passive narcissist. Her behaviour was same with her brother as well. Even with Zaid before marriage for that matter.
Then comes MJ. Obviously she is disrespectful, mean and what not. But in her and Zaid's relationship, she never was mean with Zaid. Infact she always had a nice opinion about him. Yes, she didn't want the divorcee tag second time hence agreed for his 2nd marriage but she does like him genuinely as well. That's how and why I root for Zaid and Mubashira bcz yes, she plots and plans but when it comes to Zaid, she genuinely is falling for him. Now if we expect her not to try to win him over and be cool with Ayra and be selfless in loving Zaid, that for me is quite difficult when Ayra(supposedly positive, innocent and right) also couldn't tolerate MJ and literally stops Zaid from even spending time with Zaid. She married him knowing MJ will always be there (Infact demanded to he married with the consent of his fam) So, obviously, MJ is going to create problems for Ayra. Also Zaid knows how his relationship with Ayra is. Ayra just demands and never gives..
So yes, I judge the show only based on the relationship and dynamics between the pairs. If I like people based on who is positive, negative and grey, then I can't digest most shows I guess. You just fall for a person and there's no reasoning. Person can be good bad..you can't stop.
