It seems that Arosa's family isn't quite well-off. Her parents are usually busy with heavy workloads and pay little attention to their two children. Fortunately, the residents in the Big Cave where they live are stable, all being acquaintances for decades. Even if the parents don't have the energy to take care of them, the surrounding neighbors and households on the street help to look after them.
Since childhood, Arosa followed her sister around, playing with a group of children in the Big Cave. Occasionally, there were conflicts, but overall she didn't encounter much bullying, as the elders around would be watching and intervene if there were issues.
The residents here mostly work at a nearby rock quarry company, exploiting the locally characteristic bright yellow marble for making flooring and furniture, as some wealthy families prefer this natural stone over various high-tech synthetic boards.
