I see people here judging Anu very harshly. They both insult each other and Gungun often behaves immaturely backed up by Anu's family. All her insults are ignored as funny but his one sentence is so harshly judged. He is a human he can be wrong. If Anu is batemeez Gungun is no less. He treats her the way she treats him. Gungun is not poor girl she may be pure and loving but not poor.
You don't think Anu is facing nonsense? He is emotionally forced into a marriage and is expected to not react? She also constantly insults him not family. Everyone sides with Gungun, nobody tries to understand him. The way Gungun and Akriti created a scene at his workplace is it okay? Anu had a right to be angry at these two girls but should not have spoken like that to Gungun. He accepted the mistake and apologised.
I don't think it would have mattered if Gungun was educated or not. Anu's behaviour arise from this marriage arrangement, his attraction to Gungun and his preconceived notion formed after seeing her lifestyle. His taunts about BA fail are just silly and fun banter. Ek point mil gya hai usko jispe wo Gungun ko suna skta hai bas. No other deep meaning I think.
