Saransh is a drug addict and is also a big drug dealer involved in various drug rackets. Ashish and Nandini are the ones who brought this marriage alliance between Maitree and Saransh.
Ashish and Nandini are already married, and they want Maitree to get married as well. So that she can stay in the same house, Ashish fixes up Maitree's alliance with his brother Saransh.
We see that Maitree is marrying Saransh as she trusts Nandini and Ashish and they too feel like Saransh is the perfect choice for Maitree. Maitree gets suspicious of Saransh’s behaviour on the wedding day but fails to know why.
However, she sees some weird behaviour on Saransh’s part but can’t decipher why. Now during her wedding, after the gath bandhan has happened, Nandini who is pregnant, collapses and falls and Maitree rushes to her aid.
Nandini and Ashish are having a great time at the pre-wedding rituals of Maitree but a huge mystery is about to be revealed. Little does Maitree know that Saransh is a drug addict.
