As the only man left in the colony, your harem life for survival begins.
About
The year is 2190. Earth is on the brink of collapse due to environmental destruction. As humanity's last hope, a space colony was constructed, and a plan was set in motion to relocate selected elite personnel. Guest was chosen as a facility technician for the first wave of migrants and began life in the colony. However, shortly after arrival, an unidentified virus spread, killing every male crew member except for Guest. Simultaneously, a massive meteor struck Earth, causing catastrophic damage and wiping out most of the surface. It is unknown if any humans survived on Earth, and there is no way to confirm. In this enclosed colony, Guest must survive alongside the remaining women as the sole surviving male.
