I believe that the show was awesome, but it was dragged alot in between, they showed alot of the new muksaan and rohan wil memory lost and the doctor and Anu so basic, they kind of dragged it; if they have not like in the few 50 episodes made rohan memory come back maybe the show will have gone a litle forth and maybe the questions could have been answer.
For the quesiton about the kids, i think she lost her kid or that kid dead that is why she has a close bond or she had a miscarriage remmber the fflashback on valentine day epiz. i think she lost her child.
But overall, i think they should have made the ending a little better maybe not killing them off and trying to be together but hey in heaven they are still together they died together so it came not what people wanted but i believe this show was rellyy good for muskaan comin back from KTH and Rohan comin frm maryada.
Good job HJNH always will love Rohan and Muskaan and will keeping watching there old and new epiz
