I don't see it for Mishti
Sequence of events be like -
Kunal knows Mishti is his daughter
Kunal in Khula Sand mode blasted Mauli
Kunal went home mad because he couldn't meet Mishti
Kunal asked Pari if she wants a sister
After Pari's rejection his stance towards Mishti changed, before this he very much wanted to tell Mishti about being her father but I think when Pari said that she won't accept anyone, he told Mauli that he won't take Mishti away from her...
1 When he saw Mishti on doorway he went to her but Mauli stopped him
2 Why would he question Pari like that if telling Mishti the truth did not cross his mind?
I am not saying he is wrong here, just that Pari is clearly his priority and I don't even see him getting affected with Mishti's rejection, it's like some random child is refusing him, I really didn't see any kind of pain in him... He just said that he loves Mishti, what I am trying to say is that kunal can live without Mishti, he doesn't feel the need to live with her or bond with her, this whole revelation has been the most difficult thing for Mishti and easiest for Kunal...
I am not saying "Why isn't he taking Mishti away?" I am saying that he is normal, it's like this thing doesn't matter to him.. But here everyone is like "Bechara Kunal ko Mishti dedo"
