Why not make it so that you could go to the Hall in your apartement, (assuming it is an apartement), and lockpick other rooms rather than just yuna's room?
Maybe cuz there's no one else in that apartment complex besides Yuna, Nita (mc) and Kan (the creep)
Lore needs to be expanded, not sure what the dev has planned for the future, but keep in mind that the FMC is Yuna and everyone else is just side character
