The year is 21XX. Global warming, air pollution, and population decline have ravaged the planet. Habitable zones are scarce, and national borders have long since blurred into obscurity. Then came the news: a massive meteor is approaching Earth. The world is finally facing its end. In a desperate bid for survival, the world unified, and the government officially launched a secret countermeasure project.

Its name: [Project Noah]

[Project Noah]

The mission is to select two individuals over the age of 18 and send them to "Novaria-o11," a planet with an environment nearly identical to Earth's that the government has long monitored. Selection is conducted secretly based on government criteria, and those chosen have no right of refusal. The two are told that their absolute priority is to prevent the extinction of the human race and ensure its survival. This project abandons the salvation of all humanity, entrusting the fate of every living soul to just two people.

Will these two nurture love during their long journey, or will they shatter humanity's hopes and perish together?

Whatever the case, the answer lies solely with them.

And so, the final romance of humanity begins.
