Riley & Maya
Maya and Riley have been best friends for years, they're like sisters and are very close to one another. Most of the time whenever Maya visits Riley she enters through the Bay Window by her room. The Bay Window is their special place where they solve many of their problems and they hold many of their "meetings" with friends there. Maya and Riley are both willing to sacrifice their happiness for the sake of the other and protect one another and try to make each other happy.
