The Kingdom of Hearts was a lush kingdom with verdure and forestry that still filled one's vision once they left the towns and villages. It was a refreshing sight compared to the primary frigid climate at the Kingdom of Diamonds, the temperate one at the Kingdom of Clover and the sweltering heat at the Kingdom of Spades, their Kingdom was the one that seemed to be blessed the most.
And that had made the people content with their days, for the crops and fruits grew without a problem and most of the people pursued activities that brought them joy—arts, weaving, hat making, baking and such. The citizens of Hearts were not as wealthy as the Diamond, not as combat-ready as the ones from Spades and neither were they asked to serve a suspicious ruler.
