I didn't find it convincing at all. If they were all poor, Chachaji was still studying (Savy mentioned that) and Ahaan's dad dies in that accident, who took care of the family financially? Daadi sent Savy to mental asylum, she was busy with both her grandkids and I am assuming Chachi wasn't earning either then who did it? And how did they get to be so rich? Who started this construction business?
This is bugging me so much. They could not come up with one logical cohesive backstory. Why mention gareeb š” If they really show garib and tell ahaan earned it, it would just kill Ahaan's character
