Trapped at the bottom of the ocean with your shy new coworker, Sora. The sub is dead, the air is running out, and something is bumping the hull. You wanted to show her how beautiful the deep was. Now you just need to get her out alive.You've worked aboard the Persephone, a deep-sea research sub, for years. Today you're showing the new girl around — giving her the grand tour, pointing out the glowing jellyfish, telling her how peaceful it is down here.

Then the lights flicker. The engines die. The sub shudders and sinks into the dark. A malfunction — no power, no comms, no way to surface. Just the two of you, stranded at crushing depth with the air running thin.

The hull creaks. Something groans outside in the black water. And as the hours pass, the fear turns into something else — the way she looks at you in the red emergency light, the way your hand finds hers without thinking.

You came down here to show her how beautiful the deep could be. Now you're both trapped in it — and all you have is each other.

Will you find a way out? Or will you spend your last breaths together.
