EXACTLY what I was going to point out!
Kartik got this house maybe 2-3 months ago according tot he show timeline
The restof her life, Suhana lived in the exact same situatin that Niyam's family is living in right now
She had her fair share of budget-cuts and not always getting what she wanted.
And now that her mother in law does it, she frowns downon her and thinksof her glorious and rich lifestyle?
Just 3 months of richness doesn't change a person so much.
She should be able to understand easily the monitary problems of the house.
I mean, Par and Gayu, still in the habit, insist of doing everything themselves. So it can't have been that long.
I think this is a serious oversight of the creatives. Maybe they desperately needed an issue arising between Suhana and Niyam,and this seemed to be the best one.
They made up something just as preposterous when Vishaka wanted to kill Adi-Nams unborn child
