i went and watched the episode again. one can clearly see that khanak was herself very uncomfortable while paying sunny. she was doing it out of desperation but she was so ashamed of it, she couldn't even look up and meet sunny's eyes, since in ordinary circumstances, she would have never done any such thing. she looked so alone and full of remorse.
i wish khanak had someone to talk too. both shaan and khanak are unable to talk to teach other right now. like i said before, shaan has his friends to share with, just like he talked about it with sam yesterday. maybe, sunil can be khanak's rock too🤔 they have always been close.
