One day, Tina met a man named Wall (Eero Milonoff). Intuition told Tina that this seemingly normal man was hiding a great secret. What made Tina feel unbelievable was that she was attracted to Wall uncontrollably. When the distance between her and Wall gradually narrowed, Tina was shocked to find that Wall's secret was inextricably linked to herself. Wall's existence made her realize that her orderly life was actually a lie. Whether to continue to close her eyes and live a mediocre life, or to bravely touch the truth, Tina needs to make her choice.
