i have been watching this programme from the beginning and see that Katha is not who she seems to be and does not keep her promises to the person whom she says she loves. i am sorry to say that Katha needs to look at herself and self reflect on herself to see how weak she really is and she is also teaching this to her son Arav who needs to talked to about life, how to live life and how to forgive but instead, she is running away from her responsibilities towards Viaan and her family and now has found another family to destroy. why could she not just say she wanted the money for her son's operation in the first place and none of this mess would have been created, furthermore why did she not stand up for Viaan when he needed her the most? she told Viaan's masi that she will stand by Viaan no matter what but did she? in fact the masi won her battle by splitting the two who thought were in love. Being a single mother does not mean she can ruin families by pretending she is miss know it all. she is just a week person who cannot come to terms with life and with someone who really does care for her and her son. i sincerely hope she does not ruin this family she now is in. as a mother she should help her son to come to terms with life, not run away, which is all i can see from this programme now. Viaan does not deserve Katha at all, he is too good for her. All one has to do is talk things out and work things out to resolve the matters and move forward, not run away from issues.
