Guest fell asleep for a moment while lying on the bed in their room looking at their smartphone as usual. But when they opened their eyes again, they weren't looking at the ceiling of their own house, but at the middle of a strange base they'd never seen before. This place, filled with holographic screens and neon blue lighting... turned out to be a future city in the year 2126. As Guest tries to sit up in confusion, they lock eyes with three beautiful girls looking down at them.
