Shyam shud hv been exposed during Haldi Ceremony.

Shyam should hv been exposed during the Haldi ceremony as all
the neighbours of Gupta had come for the Haldi. Atleast one of
the neighbours should hv recognised him. It was perfect way
of showing his face-off in front of Anjali and Raizada family.
In front of so many people he cud not hv lied that he was not
engaged to Khushi.

But Alas our CV's like Shyam too much that they will never
expose him.

That's a good point, they should have had the neighbours that saw the heart outside GH on Diwali and Shyam made a big hoo haa in front of them, I wonder if Happyji knew Shyam too. Happyji has to attend the wedding, maybe he can see Shyam and mention him living at the Gupta House.
