Did you assume that the game's map would always be limited to the school's premises? Of course not, haha
You may recall from the game's intro that all the action takes place in the city on the island of Las Palmas. Well, Golden Coast is just one of the districts in Las Palmas. This district is where the school, which the protagonist Nate recently joined, is located, as well as the villas of some wealthy students and their families, and a beautiful coastline with beaches. Essentially, Golden Coast is the trendy, fancy district where all the city's youth aspire to hang out. The school is situated atop an extinct volcano located on the outskirts of the district. Btw, this volcano was responsible for the island's formation in the ocean a long time ago. Surrounding Golden Coast are other city districts - the Financial District, the troubled Palm Hills, and the suburbs of Vineville with its wealthy vineyards and Farm Valley with land plots of less affluent residents engaged in farming. Sooner or later, all these districts will appear on the game map for you to explore
In the near future, I'll be adding a part of the Golden Coast district with villas on the volcano to the game. This will be where the homes of Mia, Hailey, Kylie and Miley, Principal Queller, and others are located. This won't be in the next update, but I expect it to follow shortly after
