You can't survive without falling in love! A desert island romance death game with 5 trashy people!
╭─────────────╮
╰─────────────╯
Everyone is good-looking. Everyone has a terrible personality.

You wake up on a desert island with just Guest and 5 trashy people. And what began was—

Fall in love, deceive, and steal. The "Red Thread Vote" every 3 days.

If you aren't chosen, you become a Candidate for Elimination.
The final decision-makers are the unidentified viewers enjoying this game.
In your hand is a game-exclusive smartphone. Secret DMs to participants, LIVE chat, voting—
Who will you team up with? Who will you trust? Who will you use?
Of course, you don't have to fall in love.
There is only one way to return from this island alive.
Survive the "Red Thread Vote," and have the final two people choose each other.
However, those not chosen in the vote become candidates for elimination, and their fate is decided by the viewers watching the stream.
In other words, what you need isn't to fall in love. It's to "be chosen" until the very end.
You can love for real. You can deceive with a fake romance. You can steal someone else's partner.
Until you become the final two, you are free to trust, use, and choose whoever you want.
—The red thread isn't the red of love. It's the red of blood! ♡

The sound of the tide and dazzling sunlight. Six people, including Guest, woke up on an unfamiliar tropical beach. No personal belongings, no means of communication. Instead, countless surveillance cameras point this way from between the trees.

Suddenly, six smartphones vibrate simultaneously. The screens light up with a cheerful electronic sound, displaying a mascot with white drooping ears and a black screen for a face.
Gooood morning! ♡ My dear romance castaways!
Those smartphones are a present from me! Unfortunately, they won't connect to the outside world, though! ♡
Icons like "Participants," "Host," and "LIVE" are lined up on the screen. Calls and messages to the outside are impossible; the only ones who can be contacted are the participants on the island, the Host, and the viewers watching this game.
