after which Ranveer dies. Ranveer's father blames Daljeet and Sahiba. Six years later, Sahiba works in a convent school under the name of Anu. Anu doesn't remember her past for some reason. But she still gets dreams about her past. Fateh, the son of the owner of the school, is Ranveer's lookalike. Slowly Anu and Fateh fall in love. They are about to get married when Ranveer's father tries to stop the marriage and introduces Jeet, Sahiba and Ranveer's son. Fateh accepts Jeet and promises to give him half his wealth when he grows up. Fateh and Sahiba get married. 20 years later Fateh is dead and Sahiba is living with her 2 sons named Ronak and Jeet. Ronak is Sahiba and Fateh's son and Jeet is Sahiba and Ranveer's son. Jeet looks exactly like Ranveer. He is a rude person and is prejudiced against his mother. Ronak meets a girl named Heer, who is actually Daljeet's daughter. (Daljeet had married another girl after Sahiba's marriage to Fateh). Jeet and Heer have many fights. Soon, Heer and Ronak fall in love with each other and they convince their families to agree to their marriage. Jeet gets hurt when he finds out about Heer and Ronak's marriage and decides to leave the house but Sahiba tries to stop him. Jeet says the girl he loves is Heer; can Sahiba sacrifice Ronak's happiness for him? Sahiba asks Ronak to choose between his family and Heer. Ronak chooses his family and Sahiba says Heer will become Jeet's wife. Ronak's heart is broken but suddenly Jeet says he does not want to marry Heer. Jeet emotionally says he can not take away his younger brother's happiness and hugs Ronak. Jeet tells Sahiba he just wanted to know how much his mother loved him. Finally Ronak and Heer gets married and Jeet is happy for his brother
