Aathvaan Vachan

The story is based on the life of a young woman named Manali, with a mentally challenged younger sister, Urmi.[2] Usually, a traditional Hindu marriage involves seven vows. Manali marries Aadesh, who takes an eighth vow (aathvaan vachan) that he will take care of Urmi for life. The show traces the story of their lives as a family.

Urmi's arrival to their home does not go down well with most members of Aadesh's family. Manali tries her best to balance her duties as a wife, a sister, and a daughter-in-law. Some time later, Manali is murdered mysteriously but Aadesh's mother covers up the truth and Aadesh is told that it was an accident. As Aadesh tries to pick up the pieces after this sudden tragedy, he must take care of Urmi. Gradually, Urmi begins to recover. Aadesh's family wants him to remarry but he continues to be committed to the promise of caring for Urmi. As time passes, complications arise as a recovering Urmi realises she may have deeper feelings for Aadesh. However, by now Aadesh is engaged to business partner Sneha who he connects with based on their past experiences of getting over personal tragedies. A conflicted Urmi decides to finally leave Aadesh's life so they can both move on but now Aadesh feels uncomfortable at the idea of Urmi living independently.
