I don't think he divorced prerna to appear Mahan in front of kukki. He fid that then coz he had bungled up big time. He knew prerna would never forgive him for that. Him setting pre free was an act of remorse. A way to reset the clock, so to speak.
And he did suceed in that. Prerna is with him now. And he has, by all appearances been a rock for her all these years.
So why this terrible treatment of his own daughter. My heart goes out to the poor girl. The more the makers Show kukki craving for her father and him being nasty to her, the more this raises questions on Bajaj as a father and a human.
I'm most interested in this sub plot.
Hope.... I am interested to know the reason of the distance between the father-daughter duo because, since CVs & BTSs are hinting towards Sneha going to be part of Bajaj-Sharma family soon and in such a situation, it's quite normal that viewers like us might not accept how a father who keeps a distance with his own daughter, is showering lots of love on another kid, whose identity is not known. But only because Prerna finds sukoon in Sneha he will love & care for Sneha. It's not for Kuki-Sneha jealousy track. Because, Kuki knows how dear is Prerna to Bajaj and that Prerna gets more care & attention from him than her. Yet she doesn't have a problem with Prerna. Instead, twice she informed Bajaj on how Pre got injured in pandal scene and recently on how Komo insulted Pre. So, for sure it is not for jealousy track. Hence the curiosity. That's it.
Bold - Hope..... Why did you feel that Pre wouldn't forgive him for what he did? Pre never in any of her actions or words blamed him for what he did or made him feel guilty. Infact we even got a family hug in the hospital. Pre reacted more strongly than this when she knew that Anu was hit by Bajaj's car. But after mask-knife incident, she was completely cool. 🤣 If Bajaj didn't give a divorce, even then Pre would have continued to be loyal to Bajaj as she promised him.
