A puzzle and dark mystery game. As the two main characters, you will travel through space and time to discover the mysteries of Happiness Mall.
A secret pertaining to both protagonists emerges as the truth gradually comes to light. The motive is the solution, and the truth is the riddle. The instant you believe it, you fall into the trap.
While the truth buried by the “demon” in the sands of time is perpetually hidden, a fairytale is written based on the secrets and evils of darkness.

In order to piece together the reality of the darkness from various angles, you will travel through space and time as the two main characters. Like a Möbius strip, it is difficult to tell the difference between the truth and lies.
Well-written puzzles offer hints that are directly connected to the story. In addition to advancing the plot, the puzzles provide players with an intriguing experience.
A realistic and immersive experience is created by the desolate and abandoned mall, the dim and flickering lights, and the quiet and melancholy restaurant.
