i understand this something like this ... SRK being the Raj of DDLJ and Rahul of KKH and DTPH..... i've seen many grls who wish that they have a life partner whose somethig like Raj or Rahul and so is Nupur thinking it so. ...... if we remember in the initial epi's we've seen that Nupur's been too filmy and she loves filmy characters. She actually loves to compare ppl in her life to be somewhat like the filmy characters.
As seen she always dreamt that her dream man should come in white horse(which reminds me of DHKMTN) and would take her away with him. She never thought that Mayank would b the one with whom she would share her life with ... and so she tried to find similarities between Mayank and Raj ..... as in the heroic act when he saved her from the goons, the dance and all ....... so basically she wants him to be thoda bahut like Raj(SRK) of DDLJ
atleast i believe this^^^
