Actually if kallu is leaving or living with family there is no way that it doesn't contain Anu
Anu is connected to Mr sarthak Rane. If not kalma atleast anusar will enquire about each other
Unless kalma has separated willingly after a show down and decided to part ways with consent of their respective families.
They cannot stay in complete incognito with their families as Anu sar will finally connect kalma to each other.
Like if kallu is alive she goes away without telling malhar that she is alive it is not like she will leave any alone and go anu jayengi obviously sarthak will notice her absence and would try to catch her up or even if Anu knows kallu is alive sarthak would also no and eventually malhr also would
Kallu leaving behind Anu is impossible unless she is comma
And it would be a high blunder if she just goes away with all complete study and come back after many years just to sk malhar why he shot her many years back
Also if pillu is alive to it would not be good that she left her kid for many years just due to her mu that malhar shot her
It is either kallu all alone going away many years leap
Orelse
Kallu In comma short leap with AN , then eevn Anu may blame malhar and sarthak Anu can.have a banter or sepration too
If kallu is alive and Anu also knows chances less he ki she willnot inform sarthak or just go away from sarthak as now their relationship is not as now
Don't forget other than pillu Deshmukh Rane there exist another connection between Deshmukhs and Rane as anusar they can't exactly rum away from each other and go in complete exile
But yes if it is one individual from the family ie kalayni ya malhar they can live a life in incognito without much issues.
