Homely and hard-working Archana Karanjkar marries Manav Deshmukh, a mere mechanic. They gradually come to support and fall in love with each other, despite their respective families being at loggerheads, as Manav’s mother, Savita, lied to Archana’s mother about his profession. Manav's brother Sachin dies while his fiancée, Shravani, is pregnant, and Manav is asked to take Shravani's responsibility. Archana and Manav divorce for the future of Shravani's unborn child, and Archana leaves Mumbai to complete her higher education.
Archana is now educated and returns to Mumbai after 2 years, while Manav is raising Shravani's son, who is named after Sachin. Eventually, Archana-Manav reunite and Shravani leaves abroad, giving Jr. Sachin to them. Archana has a miscarriage and Manav determines himself to become successful. He meets a rich businessman, Digvijay Kirloskar, and starts working with him.
4 years later, Manav is now a rich business tycoon. Manav and Archana now have a son, Soham, who is specially liked by Archana's childless sister, Varsha. Later, Archana delivers twin daughters, Ovi and Tejaswini. Varsha abducts Soham and they're presumed dead. Archana gets blamed for the loss of Soham as she had previously ignored Manav's warning to keep Soham away from Varsha.
Manav decides to move to Canada with his family to further his business. He sends flight tickets to Archana through Savita, who doesn't tell her anything about the tickets and misinforms Archana that Manav wants divorce.
