Shiv is also a cheater and a liar .... he is laying to Gauvri about the girl in the portrait (ishpita) .... about his first love ..... to Gauvri the women in the portrait is not in shiv's life but in reality the girl is ishpita and she is very much involved with his life ..... shiv is betraying Guavri and ishpita is betrying shiv ... i know Guavri knows that Shiv doesn't love her and is honest about that ..... but Guavri doesn't know that Shive has a g/f and is having affair .... in that way he is doing her wrong .... so good for ishpita .... if she is cheating on him .... i m happy to know ... u know what goes around comes around .... this way probably shiv will learn a lesson ......
