Can this be interpreted in this way that maybe Puja meant Krish broke the relation of Brij and Puja and she might be meaning brij when she says '' tumhare dor ka ek hissa sada mere saath rahega''.I dunno much hindi,learnt it by watching tv.But I thought as the whole diary entry is not shown from start but from the middle,then maybe she might be meaning that Krish ''u broke our(our maybe referring to Puja-Brij) relation''.Sounds too far-fetched and stupid.Still just hoping.
There also might be this angle to the story that maybe it was for krish she was writing.But maybe Krish would be the son/relation of daddaji/sangram singh or some high power family who might have sent the goons to gun her down.
What are your thoughts guys????
