Anirudh - He's been indecisive all his life. Never knew what he wanted. Before meeting Jhanak, he was in love with Arshi and wanted to marry him. However, he married Jhanak forcefully. The problem started when he brought Jhanak home from the shelter. He didn't have guts to inform Arshi and his family about what happened in Srinagar. Slowly and gradually, he started swinging like a pendulam between Arshi and Jhanak, cheating on both of them. He fell in love with Jhanak when he was about to marry Arshi. Though they confessed their feelings for each other in the hotel room, Anirudh didn't have guts to tell the family or Arshi that his feelings have changed. He didn't say that Jhanak is his wife and he loves her. Had he stood for Jhanak, she wouldn't have signed the annulment papers. Things would have been different. In the post leap, he turned evil. He came to the village where Jhanak lived. He met her and married her in a village style. But when she told him about her pregnancy, he denied that it's his child. He never thought that Anirudh was the only person she loved. He said it's Parashar's child though there was nothing between them. He left the place without her and the child. On knowing about Jhanak's death and Jhanak2 as his daughter, he's making his life a hell for her only to save his image. He also tried to burn Jhanak to save his image. Today, he:a as evil as Arshi and Srishti.
Arshi- Was positive at one time. She encouraged Jhanak to become a dancer after getting impressed with her skills. But she listened to her evil mother, Srishti and kept doubting Anirudh. She went to the extent of poisoning the minds of her in-laws, making them listen more to her than their son. Though the marriage was incomplete and had recovered from the fire accident she seduced Anirudh when he was in a drunk state. On his wedding day with Jhanak, when Arshi claimed herself to be pregnant with Anirudh's child, he didn't deny it saying this is not his child. Anirudh is no more her love, but her stubbornness to be only to be with him. Today, she is as evil as her mother, Srishti.
Aditi - Got lost in a hospital immediately after Arshi's delivery only be found by Jhanak when she was in a business, not knowing where to go after her marriage with Anirudh stopped because of Arshi. Jhanak took care of Aditi secretly and furnished the evidence to Anirudh that she is his Arshi's daughter. Anirudh accepted her. Initially, she began to crave for Jhanak after being brought to Bose house. But after getting used to the environment, she fell in love with Rishi. The same case with Aditi. She decides to divorce Rishi, but it won't take time for her to get obsessed with Rishi.
Neelu Tanushree, Abhimanyu, Mishti, and Jetu's wife are irritating characters after knowing Rishi got married to Jhanak the gunpoint. They are behaving like his family.
As for Jhanak, I would say she's stupid and spineless. She never loved any one except Anirudha though she had opportunities to move on.
