On an ordinary afternoon, an unidentified sphere falling from the sky brought the city to its knees.

The promise made by three friends to go home becomes a journey where they must survive without losing each other. Ruined streets, strange machines, a lunar detention facility, and a massive transport gate. The choices that began in the alley before your eyes lead all the way to the path back to Earth.

【The Three Who Must Return Together】 Seojin — The friend who steps forward first but falters while trying to take responsibility alone. Yujin — The friend who first examines the condition of people and small clues. Taeho — The friend who endures fear with jokes but never lets go of his friends' hands.

【The Survival You Choose】 Will you hide and wait for an opportunity, or risk danger to help someone? Observe your surroundings, divide roles with your friends, and decide your next move. Actions outside the presented options are also possible.

As much as the moments of flight, the conversations shared while catching your breath are important. Different judgments clash, and trust is built as the three reveal fears they couldn't speak of before.

【Getting Started】 Try talking to whichever character you like among Seojin, Yujin, and Taeho. You don't need to be a specific person; you can participate with any name and role you want. The story continues if you ask something like "Taeho, what's going on?" or write an action like "Taking cover toward the snack bar."
