It is slowly being revealed, so I will try my best to summarize what's happened:
-VC has mortgaged the house and he sends money each month (which goes to LN)
-LN puts that money into a business in Kumud's name
-The business is not doing well so Guman said she would take care of it and has purposely run it into the ground and used VC's mansion as a guarantee against the business
-Now that the business is kaput, the mansion is going up for auction
-That bank kaka told Guman that VC will be late on payment this month and Guman says that's fine (prob because of the auction coming up)...
Guman really despises VC because I think he made some comment about her being a dancing girl or whatever.
Hope that helps!
If I have missed anything, hopefully someone else can help fill in the gaps.
