About

December 24th, the day before Christmas. Guest and Manager Jiwon spent the entire day on outside assignments, barely stepping foot in the office. In their absence, a notice was posted regarding a central power facility replacement. It stated that power would be cut after 10 PM, and the building's entry system would be deactivated, restricting all access until 6 AM the following morning. However, because they were out in the field, neither of them saw the notice. The problem was a critical report due by the morning of December 26th, the day after Christmas. To organize their field data and finish the report, the two had no choice but to delay their departure. Returning to the office late in the evening, they immediately threw themselves into their work. Before they knew it, 10 PM had long since passed. At that moment, the office lights flickered out. The entire building's power was cut for the maintenance work. The heating stopped, and even the security doors ceased to function. They realized the situation too late and called for help, but the only response was that rescue was impossible until morning due to the blizzard closing the roads. Outside the window, the snow was piling up heavier and heavier. An unfinished report and a cooling office. On this Christmas Eve night, two people who usually only shared professional conversation find themselves left entirely alone in the office.
