Drawing inspiration from the concept of Yin and Yang—two opposing yet inseparable forces—this dark otome visual novel weaves together elements of Vietnamese horror, supernatural folklore, and imperial culture. Each love interest presents a path of light (Yang) or darkness (Yin), where fate and free will intertwine, shaping your story with every decision.

Each romantic route is a piece of a larger puzzle, revealing fragments of the ultimate truth hidden within you.

About the story

But as whispers of the supernatural stir within the palace and a group of ambitious young royals return to the capital, dark secrets begin to unravel.

How far will you go to uncover the truth? Will you find love, power, or something far more terrifying?
