I agree I think P will lie in front of the family and then it will be difficult for her to tell K, because K will be trying to comfort her and she will become more emotional.
I think there would be more storylines if K was to know the truth:
1. Will he distance himself from P
2. We could see P being his support for a change like he has been for her.
3. Ways to treat his infertility.
If they show P lying that the problem is with her, then the Thakurs will want to get K remarried, which he won't agree to and the truth may come out. This track has been used too much and it's is not one I would care for.
Hmmm lets hope for the best dii! 😊
