I feel, and this is just a personal opinion, that it would have been really great to see if Rhea was a positive character who accepted Ahaan and Ishqi's love without any tricks or whatsoever. Drama wala kaam daadi ko hi karne dete. And she would get a job and be a single parent. It would be very beautiful.
Koi zaroorat nahi thi usko esa negative dikhane ki - "gold digger" and everything.
