There are some incidents inside the purple house. The landlady calls us to investigate. But since there are so many houses in the area, we first asked about the most prominent feature of the house. He told us that the exterior of the house is purple and that we can recognize it. Because we knew we had gone to similar architecture houses before. When we got home, he mentioned a missing case. He mentioned that a few valuable items had disappeared a few days ago and had difficulty finding. He offered to help us, and we accepted it.
