Sikander Kundra(?)

hey had this doubt... does SK mean Sikander Kundra?
if it is Kundra then Rishab shud have taken his step father's surname... which i feel is unlikely with the antagonism he has for his step father.
so will it be another surname starting with K to stand for the shortening as SK?
but then another possibility niggles... and with it comes a chance for a filmy flashback track... what if Rishab's father is related to his step father? like a brother or cousin... then the surnames will be same...
so did RK's father have a natural death? OH! my mind has gone all filmy😆😆😆...
just hope we get something gripping from the entry of all these characters ... with the story not deviating from Rishbala, which goes without saying...

a J step bro wo line mars babhi...
whose wife in turn line mars her devar😕😆 ... makes Madhu feel possessive?
a sweet , bubbly sis who is opp to trishna and shows the softer side of RK to madhu.. .. who in turn will expose Madhu's bubbly side to RK...someone who will help Madhu to understand him better, may be even tease to flirt with her husband... who will initiate the first fluttterings of Love?
