Dev, Disha's dad, gave up his life to save Rano. I really wish he hadn't. His sacrifice made things even worse for Disha. Rano wants to ruin Disha, and even though Disha had gone into Suhas's good books, she is not n e more.
In the long run Disha lost her father, a person who had supported her. She had begun to hate DK bcuz he had been linked to Dev's death. Disha lost her sister, and found an enemy.
