The lack of self awareness Dev and ishuwari have.
It genuinely blows my mind how these two can never see their wrong. They can never reflect on their actions. Matlab atleast make a list of all the wrongs you guys have done to each person because it's a lot. They have a serious case of main character syndrome. (Where you think you the most important person and noone else matters)
Neha and ria don't even visit Dixit house. Even on raakhi. Whereas Saurabh and Sona talk problems out. Ishuwari did something seriously wrong that her daughters don't bother with her at all. And she's the least worried about that. Never even seen her call the other 3.
Dev on how bijoy only judges him. Bhaiya Aapne konse mahan kaam kiye Hain Apne father in law ke liye. You slapped him, you didn't save his lifetime JAMA punji his house. Apparently Dev wasn't even there when ASHA passed. Toh what has Dev done for bijoy.
Sonakshi has saved ishu from the whole khatri matter. She was her nutritionist and even after marriage took care of her. If ishuwari can't accept sonakshi even now how on earth Dev expects bijoy to accept him . (If I was related to sonakshi I wouldn't accept Dev like ever)
Ayush and Soha keep telling their feelings to Dev and he doesn't understand. It's like it doesn't even reach his brain.
Ishuwari thinks Dev is hira husband because he took care of kids for few months.
Ishuwari looks down on bijoy as if he is bad. Aankhe kholo toh Zara pata chalega how he is the best father , a much much better husband and a so much better father in law. (Only one moment ishu realised how well bijoy treats ronita when bijoy said "ronita ki sirf ek cheez nhi Pasand uska husband" and laughed. )
Ishuwari still believes she did right despite, mamaji, Sona, Dev aayush and even Soha being against her. Behen itna confidence Kahan se laati ho. Considering her past track record of terrible relationships with her son (yes she manipulates him made him loose the love of his life, than his daughter) her daughters that she still doesn't build the bond with, her daughter in law , her poti now , her samdhis.
(Also shout out to the beautiful person that messaged me how I am a fake feminist. Aap hi bata do kaise feminism chalta hai feminism ke gate keeper)
