Au that’s sort of like 'Sophia the First' premise.
Gon and Mito have always lived in the peasantry class, where life was difficult but they stuck together like thieves and made recreational fun with the other peasants around by making fun of the higher class aristocrats and nobility and all their lazy butts and excessive pomp and circumstance in their lives.
But then a letter was sent to tell Mito and Gon that it has come to the government's attention that Ging is of nobility standing, and as his family, they're sending their bank account info with their reserved fortune, and people to guide them to their new home in aristocrat road.
Mito and Gon both don't wanan go for multiple reasons, Mito doesn't want to be associated with Ging in anyway and his belated efforts in taking care of them, and Gon doesn't want to enter the stupid extravegant world of the nobility and all their judgey, ignornat ways.
But the other peasants have already began to treat the Freeces with contempt since they're of a higher class, so they might as well move. Gon is still against it all but at least they live on the Zoldyck Estates where there is a pretty fun and gorgeous teen on the lot, even if all the other families on the estate are just as uppity as he thought
