Well it's already more or less clear from the teasers that Amber's boyfriend and Minhal are going to get married.
Amber's reaction at his house was kind of expected. You see she didn't think beyond her love for that guy. She never realised that she would actually have to adjust to his life style.
Amber was raised like a princess and on top of that she's the only child of Malik Sarkar so you can imagine how pampered she must've been throughout her life. Balaj and her were the only children in the house and both of them must've been spoiled with love, affection and luxury.
I think practically, Amber can't adjust with that guy because she's simply not used to that kind of life style. It would be very hard for her to adapt.
It's kinda like saying that Balaj should move into Hooriya's house. He would never be able to live there.
I actually like the pairing of Amber and her boyfriend, they should get married, the reaction of Amber at the guy's house was weird, it seems like she cannot adjust with the lifestyle of his and the facilities he has at home
I like the character of Amber, but she seemed strange in that scene and her boyfriend's mother seemed sweet to her
