Maitree and Nandini are best friends and, to avoid being separated from each other, hope to marry into the same house.
Nandini and Maitree are now grown up. Nandini is married to Aashish. They are also expecting their first child. Aashish is an advocate by profession. Eventually, Maitree marries Saransh, Aashish's younger cousin. Unknown to anyone, Saransh is a drug addict. Saransh and Maitree; Nandini and Aashish get into a car accident. Aashish and Maitree luckily survive the accident. Nandini falls into a coma after delivering a baby boy while Saransh succumbs to his injuries and dies. Saransh's mother, Sona Tiwari blames Maitree for Saransh's death. Nandini's mother, Advocate Vasundhara Singh Rathore accidentally mentions in front of Aashish that Saransh was a drug addict, which shocks him. Maitree decides to take care of Nandini and Aashish's son. Vasundhara informs Maitree that Saransh was a drug addict. Maitree is devastated and confronts Aashish. Aashish tries to conceal the truth but fails as Vasundhara has sent Saransh's reports to Maitree.
Aashish gets arrested and Vasundhara uses false evidence in court against him to prove that he is a drug dealer. But later, he gets bail and attends his son's naming ceremony. Aashish and Nandini's son is named Nandish ( a combination of their name). Maitree and Aashish decide to raise Nandish.
Nandini comes out of a coma and tries to bond with Nandish, who doesn't want to get rid of Maitree. As a result, Nandini turns against Maitree and starts to think that she is snatching Nandish from her. She tries to create difficulties in Maitree's life and turns her enemy. After a series of events, Nandish accepts Nandini as his mother but continues to refer to Maitree as "maa" (mother). For Nandini's happiness, Maitree leaves the Tiwari Mansion. She meets a fun-loving man, Harsh, and marries him. Later, it's revealed that Harsh is Saransh's half-brother from his father's side. Both Maitree and Harsh move into the Tiwari Mansion again. Harsh's mother, Kamna, tries to torture and kill Maitree but is exposed. Aashish dies, in an attempt to save Nandini from a fire. Saransh who is alive turns furious when he discovers that Maitree has remarried. He returns and pretends to be Aashish, to seek revenge on Maitree.
Maitree gets pregnant and gives birth to a boy child. Saransh steals the child and misinforms the family that he has murdered him. Harsh blames Maitree for the possible death of their son and throws her out of the Tiwari house. Saransh hands Maitree's child to a greedy woman, who leaves the child in the trash. Maitree finds her child and decides to raise him, but she is unaware that it's her biological child.
Maitree lives with her son, Swayam. On the other hand, Harsh still blames Maitree for their son's death and has adopted a girl, Juhi. For the sake of the family, Harsh and Nandini get married. Maitree eventually got engaged to her boss, Yash. Saransh comes back and tells Maitree and Harsh that Swayam is their son. However, due to Swayam's illness, the doctor tells Harsh and Maitree that they have to produce Swayam's sibling who will donate bone marrow to Swayam. Maitree and Harsh reconcile to save Swayam's life. Maitree breaks her engagement with Yash and Nandini breaks her marriage with Harsh. Nandini gradually realizes she committed a grave mistake by breaking her marriage with Harsh to save Swayam's life. She turns revengeful and joins hands with Saransh to kill Maitree. Sona learns about Nandini and Saransh's plan to kill Maitree. As Sona calls Maitree to expose Nandini and Saransh, Nandini pushes her from the terrace, and she dies.
