Malhar loves playing revenge revenge right if he actually wanted to avenge Swara's death should have married Goda instead of Kallu.
According to the diary Aao Saheb and Vivek are the ones who did the actual kaands Anu just silently watched everything.
Both Aao Saheb and Vivek would have been directly affected by Goda but they don't give a damn about Kallu.
But Kalma are the lead pair and we all love them so they somehow have to get remarried but the love/hate drama make no sense at all.
