Along the way, she discovers that everything may trace back to the writings of Yeong Cheol, a web novelist whose fictional worlds are beginning to bleed into reality. As the boundaries between fiction and truth begin to blur, Ha Ni finds herself trapped in a labyrinth where even she can no longer tell what is real.
Sang Hee, a woman weighed down by the quiet collapse of her marriage, seeks solace after growing distant from her husband. At a friend’s suggestion, she visits a place said to offer healing, but what she finds is a dreamlike reality where time, space, and memory become uncertain and disjointed.
Dong Seok, her husband, begins to sense something is wrong. As he follows the faint clues his wife leaves behind, he too becomes entangled in a series of surreal phenomena that defy explanation. Meanwhile, Yeong Jun, a man who once came face-to-face with death, discovers he can drift into the memories and inner worlds of others.
As tensions rise between Ha Ni and Yeong Cheol, the people around them are pulled into an unraveling reality, where illusion and memory collapse upon one another. Dong Seok enlists Yeong Jun’s help to find his wife, but both men slowly come to realize—they may have lost the way back to reality long ago.
