He married Lovely while he was married to Nimrat. Left her alone in village and never looked back. He went to village and asked only mama. He still not trying to get info about Nimrat. If he really wanted to know he would know ...Nimrat had a daughter. Mama-mami will not tell him. Villagers will. You see he is also a culprit here.
I guess Kulfi too has a distrust and insecurity regarding this. A guy who can marry another woman even after having a wife...who will trust him? Sikka is a criminal. This is his punishment. Lovely and her nazayez child is his punishment. He did a nazayaez shadi with this lady Lovely. Now he is taking responsibility of that lady's nazayez child Amyra. As a woman I like when he suffers. A man like him should suffer like this. A man who leaves his wife and child to stay with someone else should suffer like this.
He got his first slap when he learned Amyra is not his daughter and whatever Lovely said was all "Lies". He thought he used her...but he was the one who was used by her. So that slap was right for him.
It looks like he will know the truth after sending Kulfi to bording school. That will be another slap for him. He started a nazayez shadi with Lovely. He carried her nazayez daughter...and now for that nazayez daughter he lost his zayez daughter too.
Sikka is paying for his crime. The dhoka he did to Nimrat.
But I am feeling sorry for Kulfi. Why should she pay for something she didn't do? I was happy when she was with Tevar. I willl be happy if she loses her memory and grow up in a family where everyone loves her. Sikka may run throughout his life to find where is Kulfi. Amyra and Lovely would get a punishment too. They send Kulfi out ...but still Sikka is not Lovely's...nor he loves Amyra anymore. This is how all the criminals Lovely, Sikka and his family...including Amyra would get their punishments.
