In the year 2150, Dr. Edi, a player-controlled character, joins a pioneering medical research institute to explore a revolutionary therapy for depression known as Dream Remodeling Therapy. One day, while in the dream archives, Edi accidentally breaks a jar filled with colorful candies, setting off an alarm. Unbeknownst to Edi, the jar and its contents symbolize the dreams of a patient named Nora. The shattered jar releases a powerful energy that pulls Edi into Nora's dreamscapes.

Each dreamscape represents a cage filled with trauma and shadows, each with its own unique locks and keys. To navigate and re-materialize these dreams, Edi must find the corresponding lock door and key in each scenario, guiding Nora out of her emotional turmoil and helping her reconstruct her dreams. These locks and keys symbolize various concepts, such as childhood traumas, environmental factors, and personal struggles.

In these dreams, Edi takes on different roles, such as Nora's friend, family member, depending on the scenario. This fluid role allows Edi to intervene and support Nora from different perspectives.

Upon successfully reassembling Nora's dreams and returning to the real world, Edi gains access to the dream archives, where numerous other dream files and lives affected by depression are stored.

Years later, Edi coincidentally encounters Nora on a city street. Although Nora does not recognize Edi, she responds politely and shares a smile. Nora's friend, who is with her, gives her a reassuring pat on the shoulder, and they leave together. Edi, witnessing Nora's return to her normal life, leaves with a profound sense of awe.
