Is it Priya and her mother's plan????

I think it's Priya and her mother's plan to get married Rehan. She definitely doesn't want to get married Soumya's boyfriend. She only wants Rehan and take her revenge.

I think mother and daughter outsmarted Rehan. They calculated his move easily and it's also predictable.

Like a dotted brother he married Priya to keep soumya happiness enacted.
