Suddenly, an unknown businessman named Saurav Singhania (Karan Singh Grover) enters their lives. Saurav, who shows interest in Aditya's company, makes them an unbelievable offer. What follows is Aditya and Siya's struggle to uncover Saurav's real intentions.
Aditya and Siya are very compatible. In fact they are so blissed out they seem to be in a permanent honeymoon. Both of them open a Vikram Diwan memorial hospital in the name of Aditya's older brother who has died in a plane crash. In fact even Siya married Aditya, she was engaged to be married to Vikram. You even hear that she was pregnant with Vikram's child and when he dies in the aircrash, she marries Aditya. Eventually she miscarries.

At one stage Aditya lands in prison. Siya then has no choice but to go to Saurav for help and to remove her clothes and pride to saurav. And in the morning, she asks Saurav for Aditya's freedom.
When Siya sees a tattoo on Saurav's back she realises that the man who she thought was a stranger is no stranger. The tattoo is identical to the one her first love and Aditya's elder brother Vikram had on his back. While Siya confronts Saurav and asks him if he is actually Vikram and whether he has had plastic surgery to change his looks; Saurav tells her she will never know the answer to this question in this lifetime.

He is handicapped but he has told his friend Saurav about the betrayal of his brother Aditya and his fiancee Siya.
