Shalini's (Rucha Gujarathi/Kali of Kkusum) father, played by Harsh Chhaya (Dr Manas of Astitva), is shown to be an alcoholic who can't look after his wife and his family.
In fact, when Shalini gets molested, she falls from the top floor and is severely injured and that's when he realises how irresponsible he has been and decides to rehabilitate himself.

I watched tonight's episode. It looked realistic. Good acting by all characters.
