Concept of Kitani Mohabbat Hai 2 - i.e Hero is a Don and Heroine belongs to a family of Police Officers- is similar to a Tamil Film 'AmarKalam' (1999). Even Heroine's chatterbox role is the same.
As few have already posted that Arjun may be an orphan... I think the story will go in future like this.
Combining KMH2 and amarkalam😃:
Arjun is an orphan and he his brought up by the Singhanias
Arjun's So called Dad is actually a friend of Arohi's Dadaji.
He is an International drugist and Mafia leader who comes with his pregnant wife(may be he had another love life) to stay with Arohi's dadaji.
Dadaji gets him arrested and his wife leaves him becoz of that.He never meets his wife then.
This Creates a vengeance in his mind for Arohi's family. He wants to disturb the happiness in arohi's family.
So he asks Arjun to Kidnap Arohi for a while. Where Arohi falls for him.
Knowing this Arjun's so-called-Dad asks Arjun to fakely love Arohi so that He can totally ruin Arohi's family.
But Arjun starts loving her actually.
When Singhania faces Arohi's Dadaji and tells that You have to suffer for what u have done to my family,Arohi's Dadaji tells that Arohi is actually singhania's daughter!!!!
Shocked singhania asks arjun to stop the drama but Arjun who is deeply in love😳 with arohi doesn't agree.
So singhania tells arohi that arjun is faking with proof. 😡
But the lovers later unite.
But Both DON's family and Police officers' family wants to separate them . They go to an extent of killing Arjun...😲
At the End...All is Well..Arjun and Arohi unite and live happily ever after.😛
Note:Amarkalam is one of my all time fav movies. Hope they will take KMH2 with out ruining the beautiful concept.
