I know this since I've watched parts of JA. I have personally never blamed Paridhi. I knew that she's capable of handling intimacy. What she said no to was I think, showing excessively intimate scenes like consummation etc which is OKAY.
No one wants to see that anyways. She would never say no to simple hugs or simple romance. Sab KK ka kiya dhara hai!
They were the ones who didn't care about Hanita. No songs, no romantic scenes and no specific focus on them in the storyline.
We all know how much she respects AD and loves Ashnoor and vice versa so offscreen bond ka koi sawaal hi nahi hai.
