I agree with all of you - Myrah definitely doesn't know Rudra. She only knows that he's a widower, her odyguard, a good dad, has a temper and still is mad love with his wife. This is all superficial - anyone who would talk to Rudra for 5 minutes would know this. Her falling in love with him is just her dream of how someone would love her the way he loves Paro. She doesn't know his fears, his guilt, his tumultuous relationship with his mother, how he and Dilsher lived alone for 15 years, his patriotism for his country, I can go on and on. Does she know about any of this? Has she tried to know more about his life?
People go blue in their faces and say that Paro fell in love in a second and she did BECAUSE of their history together through that doll. Once she saw that, all the pieces in her puzzle (life) fell into place. Until then, she was grateful to him for being her rakshak, but once that gudiya showed itself to her, Paro fell in love. There was history, a deep connection and justification. Even if the doll connection wasn't shown, Paro was always compassionate and ready to know about Rudra. Remember when she apologized to him about wanting to hurt him about his mother's abandonment? Even when she hated him, she didn't want to cause him pain. After she fell in love, she saw his soul and his bitterness as a mask of his pain. She actively sought to calm and heal him.
So of course Myrah doesn't know Rudra and never will. Rudra seems to only have feelings for her based on her looking like Paro and her 6 "different qualities" from Paro (yeah right). Nothing about Rudra and Myrah together makes any sense. Then again, with the show wrapping up so soon, there's no room for logic or consideration left. :(
