Now looking at the videos one thing is clear, Vikas borderline tortured Gauri to take Parth's name. Vikas can and did go to any extent to destroy Parth's name and career. This puts the entire "note" from Niti into a perspective. I mean, I'm not saying she was also tortured and was forced to put out a note against him but still... just puts her situation into a perspective POV. Anything could have happened. Job ( she got PTKK) , money, jealously or... may be, just may be she was forced. I mean this man wrote articles and police complaints. So I wouldn't be surprised...he's capable of anything.
About Utkatsh and Ayaz...they didn't seem forced. Cause they hit Parth again and again... their actions came off really vindictive. Where else Niti, except for that "one note" against him she didn't say anything. She even in a IV after that said she wants to forget everything and move on and even wished him good luck for his movie. And she's standing by her words till now. She has cut off all sorts of ties with KYY. ( smart I must say, really good for her)
Anyway this is just a observation. I don't know anything for sure...just an opinion. I just wish both of them good luck for their future endeavours.
