you didnt saw the last episode... I thought she was 2nd lead but she was also killed in a bomb blast... Arjun was alone till last episode.... And found the evidence of his wife killer on the last episode and went in search of the killer....the ending was abrupt....everyone thought that season 2 will come but due to covid it was an off project now....I wish the situation get better so they can bring season 2.....
I know the ending even though I did not see it. To me there is no point in s2 if Riya (Sana) is not coming back. They had a revamp of the show briefly with like a new supporting cast, but it didn't work well.
