I understand Hardik wants to save Gulli's respect, so offers his hand in marriage because he knows he likes her. But ...
1. They both know each other since a few days. What do they really know about each other that they can decide to marry? Subhadra was right 'tum iske baare me jaante hi kya ho'. She meant Gulli's past, but I want to ask him about Gulli as a person. Does he really know her well?
2. What does Hardik do for a living? He looks too young to be earning money. Don't Gulli's grandparents want to know about the guy and his family? Aise hi shaadi karadi. What does Anandi and Shekhar family know about him? They never knew about Subhadra's existence a few months before, have never met Hardik's parents and they are vouching for Hardilk after meeting him for what, one hour?
3. Hardik's parents. Anandi mata keeps singing praises about parents and respect and what not, doesn't anyone think about asking or atleast informing Hardik's parents about the wedding. Why hurry for the wedding like it is now or never?
4. Hardik and Gulli are living at Kesar Bagh. Why? How will Hardik take care of Gulli if he doesn't have a house? Again, does he earn any money?
