You awaken in a decrepit old mansion with no memories, no concept of self, and no certainty that you are even alive. A woman with jade eyes who calls herself the Maid informs you that you are the Master of the house. She offers to guide you through its lifeless halls to witness the tragedies that have befallen its former residents, suggesting that among those memories, you might find some trace of yourself.

The journey unfolds through a series of doors, each opening onto a different era in the mansion's history. Beyond the first door lies the year 1603, when the mansion was known as Rose Manor. In this era of flourishing art and theatre, the inseparable Rhodes siblings live in the gardens where roses bloom abundantly, though not everyone is content to see them happy. This arc centers on Mell Rhodes, a mild-mannered seventeen-year-old with flaxen hair who cares deeply for his younger sister Nellie. His life changes when a mysterious white-haired girl with red eyes arrives as a servant, leading to a forbidden romance and dark revelations about his family's past.

Beyond the second door lies 1707. The mansion lies in ruins, and a beast dwells within who claims to yearn for a life of serenity, though he soon yields to his innate savagery as a massacre ensues. Beyond the third door waits 1869, a technologically advanced era of railways and industry. The mansion's master is an ambitious businessman named Jacopo Belsatti whose obsession with wealth and power leads him to neglect and mistreat his wife. Beyond the fourth door, the Maid tells you, is the final tale the year 1099. Here you see a young man who claims to be cursed and a white-haired girl named Giselle who has been branded a witch and marked for death.

Having witnessed these four tragedies spanning different times and places, you are free to choose whether to end the story there or press on. Yet as the Maid implies, you were able to bear these stories because they were not your tragedies. Behind these doors lies the story of the mansion itself a cursed place where the souls of its former inhabitants remain trapped, their suffering connected across centuries. The protagonist, who awakens with amnesia, is gradually revealed to be central to these events, his own forgotten history intertwined with every tragedy witnessed.

As the narrative deepens, the focus shifts to Michel Bollinger, the amnesiac protagonist, and his connection to the mansion's curse. The story explores themes of identity, trauma, and redemption, revealing how the mansion became a prison for tormented souls bound by cycles of cruelty, vengeance, and despair. The Maid, whose own role proves far more significant than it first appears, guides you through these revelations, challenging your understanding of victim and perpetrator, love and hatred, and whether forgiveness can ever truly break a curse born from centuries of suffering.
