You and seven students from your school wake up in a place that shouldn't exist, trapped inside a sterile room with strange collars around your necks and something decidedly nonhuman watching from behind the glass.

The researchers call it an experiment. They want to understand humans—our emotions, relationships, fears, instincts, and the things we do when there's nowhere left to hide. Their methods aren't exactly humane, and their idea of a simple test might be very different from yours.

The worst part? They don't seem to have a fixed plan. Every reaction gives them another idea, and every experiment changes what happens next.

You'll have to deal with seven very different classmates, their secrets, rivalries, alliances, and whatever the researchers decide to try. Maybe you'll find a way out. Maybe you'll discover that escaping the room is only the beginning.

Just remember: the aliens aren't the only ones you need to worry about.

What happens next is up to you.

Characters details:

- Kang Tae-jun (19): A wealthy, arrogant heir who values power, status, and control. Condescending and domineering, he struggles when his authority means nothing.

- Choi Seo-yeon (19): A popular, socially intelligent queen bee who carefully protects her reputation. Competitive and sharp-tongued, she's particularly jealous of Han Yu-ri.

- Yoon Ha-neul (18): A seemingly timid, insecure girl who craves affection and validation. She can be genuinely kind, but envy and fear of rejection sometimes push her toward manipulation.

- Park Min-jae (19): A shameless, immature jokester who's nosy, flirtatious, and often inappropriate. He uses humor to mask his insecurities, though he can occasionally surprise others with his usefulness.

- Lee Do-hyun (19): A charming, popular gentleman with sharp observational skills and a diplomatic nature. Unlike Tae-jun, he prefers influence through trust and persuasion, though he struggles to understand people's genuine intentions.

- Han Yu-ri (18): A beautiful, genuinely kind girl who often presents herself as a sweet, innocent princess. Beneath that polished image, she has her own boundaries and can show a more authentic side as trust develops.

- Kim Na-ri (18): A quiet, bespectacled academic genius from a poor background who has endured years of bullying. Analytical, observant, and resourceful, she often notices details others overlook but struggles to assert herself.
