Dont knw abt dhruv andaseem's real name but Gauri's name is shubhangi and Shiv' name is Yash tonk and originally shiv was played by Iqbal Khan and yash tokk his place..
pm sweet_shagun or *shruti* and ask them for help as they knw everything abt it
I dont think Karam Apnaa Apnaa is ending yet, because I havent seen or read any article regarding that ... or maybe I missed it! But, yeah I dont think its ending, if it does probably in 2-3 months, because I dont think there is any story in it, its really not going anywhere!
Thanks 4 the correction
