I think brijesh is responsible for all the bad things that happened to Nahar.
Brijesh is not what he appears to be. He has ruined Nahar's life so many times.
1. Not accepting Chandani
2. Not telling Saloni about Chandani before marriage.
3. Not telling Saloni when she left Nahar about how Chandani died and let Nahar take the wrap for it.
4. Even after Nahar went to prison he did not disclose how Chandani died and who is responsible for Chandani's death.
5. Brijesh is responsible for accident, Nahar's imprisonment.I don't know whose skin Brijesh is saving by keeping secret about Chandani's murder That was the reason he was blaming Saloni for Nahar's accident.
6. He made Dheer the enemy of Nahar. In reality Brijesh behaved as Nahar's enemy and fixed his marriage to Nilima without Nahar knowing it.
There is a lesson to be learn here Do not control younger brother/sister or children's life to the point that you ruin their lives.
