Ever since Christmas, Jin had wanted to renovate the Shop Instance so his new customers would have a better first impression while his repeating customers would have a more inclusive experience using it.
He had been experimenting with new interior designs inside the Dungeon Maker and felt that the ones he found had been extremely inadequate. It did not feel right when he tried to balance the needs of the masses while trying to do a makeover to give a better aesthetic to the whole Shop Instance. There was no sense of closeness or familiarity if something was too grand in his designs.
It was only after the Demon War Defence that it clicked inside of him that there was actually no reason to create an interior design. If it was an instance like all others, so why should he restrain it as part of a building? With more resources in his hands, Jin could create something quite different from his past designs.
