Really Yes, he would have kept Naany for his children instead of marrying her. But family people made him to accept for the marriage, they want their son smile as before. But he loves his dead wife this much.
I don't know really whom we criticize?
One side, his family though they know his son's mentality, they forced him to marry. He too accepted only for kids.
Now this much is happening for Arthi. They not even asked him once what is the reason. Or they can telll him that he should not behave with his wife like this though he is angry. Remember, the same parents praised Arthi in older episodes.
Now Yash is Angry ok, for that also they r blaming Arthi. God, nobody is supporting her at least for courtesy.
Other side Shobha family , God they did very big mistake by lying that Arthi is Widow.
And other side Yash, Still don't know the reason why he is Angry. But this much anger, no girl will be able to bear it.
Now Arthi, she should leave the house at least for some days. then really Yash will feel something bad abt himself that he acted very rudely with Arthi.
