first the song
baatein kitabon ki
raathein hai khawbon ki
now the symbolism
prithvi was in the library reading book after his heart got broken, maybe thinking.... baatein kitabon ki...
you know... after a break up.. you start doubting love for a while to get over it and stuff... well prithvi just lost the only girl he loved....
and he then stares at the night sky... raathein hai khawbon ki.....
his dreams are in the night sky...
well that's that...
