Trapped inside the world of "Praesepe in a Cage," Yun Juyeon becomes the game's female protagonist, Praesepe, and must navigate a tangled web of romance and danger to escape. After completing all five male protagonists' storylines, she's thrust into "secret mode," where everything changes. The characters she thought she knew are acting strangely, and Praesepe begins uncovering secrets—memories, death, and a mysterious new ally named Grand Duke Fenrick. As she gets closer to finding the "real" male protagonist, Praesepe must decide who to trust, and whether escaping the game is truly the freedom she desires.
