Don't you guys think Kajjal is similar to the movie "Kal Ho Na Ho". Here Saif is Dhruv. SRK is Dev who is going to die. In the movie SRK lies that he loves Sonali Bendre. Here as his wife is dead, he lies that his love is lust. Its kinda similar. Now Kajjal will say yes to marry Dhruv and just prior to the wedding something will happen to Dev maybe he will get sick just like how SRK gets sick and Preity & Saif find out...here Kajjal & Dhruv will find out that Dev loves Kajjal and lied just to save her life.
Its going kinda same path as Kal Ho Na Ho.
