Heroine says, Baba mujhy apna Subah ka Sitara kehty thy and after some sentences hero says Me ne Subah k Sitary se shadi krli.
I m 100% sure CVs had watched this scene before writing Asya's terrace-star naming scene because hero always compares his ladylove with moon and this was the 1st time (actually 2nd) that hero compared his girl with star so I personally believe that Asya's star naming scene was a copy (to much extent) of above mentioned scene.
