Description：

When Ethan randomly wins a lottery for a murder mystery game called "Memorial Academy," he reunites with his four old friends for what seems like innocent entertainment. But as the mystery unfolds, the scenario begins to mirror a real tragedy from thirteen years ago—the death of a girl named Jade White, whom everyone had dismissed as suicide.

Trapped in a sealed room with rising chlorine gas, the friends are forced to confront buried secrets and unspoken guilt. Each revelation strips away layers of deception, exposing how Jade was systematically destroyed by jealousy, cruelty, and abuse—and how one person harbored the darkest revenge.

This is not merely a game. It's a carefully orchestrated judgment, where justice doesn't follow the law—it follows the heart of a man who loved and lost everything.
