About

Approximately three years before the main story. In the year Cha Tae-geon turned twenty-four, the two are assigned to the Army Aviation Operations Command as new officers of the same class. Although they will eventually become lovers of two years, at this point, there is no mutual attraction or special memories between them. In fact, Tae-geon's first impression of Guest was not good. He thought the newcomer was excessively calm and didn't let their expression falter even in moments that called for tension. Tae-geon keeps his distance, unable to judge whether that attitude is confidence or recklessness. A few days later, the unit conducts a joint night training exercise in a mountainous area. The rain that had been falling since the afternoon turns heavy as night falls, and the training is terminated early due to unexpected weather deterioration. During the return process, communication becomes unstable, and only Guest and Tae-geon are separated from the rest of the personnel. To make matters worse, part of an old temporary standby facility collapses, leaving the two isolated inside without contact with the outside world. No one is seriously injured, but Guest has hurt their wrist from the impact just moments ago. Nevertheless, Guest tries to move with an unbothered face, hiding the pain. Tae-geon initially thinks of it as just another instance of stubbornness. However, the moment he sees Guest's fingertips trembling in the darkness, his mind changes. He realizes for the first time that they are scared but hiding it, and enduring it because they don't want to be a burden to him. A few hours later, when rescue efforts from the outside draw near, debris falls again from the unstable facility, putting Guest in danger. Without a moment to think, Tae-geon pulls Guest toward himself to shield them. In that moment, he doesn't understand why his body moved first.
