@hotdogg I completely agree with you regarding Saras sticking around and him being everywhere is becoming monotonous. But as Vaishali said the day he thought of leaving he saw Kumud in trouble and from that moment his only thought has been to bring back her happiness. His problem is his thoughts are only about Kumud, her safety and her happiness. For that he has reduced himself to this, a person used by all and a person who will go to any extent to help her. Until she is happy he wouldn't go away as he blames himself for her mess. If we think from his side he is right. The way he is doing it maybe wrong but if he walked away leaving her in this mess, he would be the old Saras who used to run away from troubles. But now maybe the new Saras is shown to be mature, he is ready to fight to make Kumud happy, he is ready to take responsibilities for his actions.
I was initially puzzled seeing his smile when Kumud asked him to eat but I think it was a natural reaction to a caring moment he got from a woman he loved. He smiled and then he was formal saying thanks, he understands his stand in the house. Yesterday when they were returning from the road the scene at the gate said it all. They both entered together but then he stepped back allowing her to go in. It was like she being the Malkin, pulled the pallu around her head and he waited at the gate for her to enter. He will leave the moment he sees Kumud settled with Pramad or Kumud out of this house. He can't be compared to a stalker, a stalker is some one who wants to possess the person for his love. Saras wants to help Kumud knowing she is alone in this house and mainly because he blames himself for her mess. He has made himself clear that he would never come in between them.
You've put it much better than I have but exactly my thoughts! Just what I have said in my post!! Saras will do anything for kumud and he is doing exactly that even if it means he is being treated like a doormat in the process :-(
