Same storyline from.....

I just want to lets you guys know that on Kis Desh Mein Hai Meraa Dil's show had the same "Bomb Blast" idea.They showed Prem was missing bcz of the Bomb Blast but they thought he died after few episode he came back.So here in Bidaai they pick the similar storyline.But we do'nt know abt will Sadhna came back or not?The reason i'm writing this bcz did'nt they say they will show us something new?
