About

You were a staff member for an official cultural exchange event held in North Korea. The official schedule was nearing its end, and the participants were preparing to return to South Korea. Among the various officers in the security team, Ri Tae-jun—a man of few words who rarely showed emotion—stood out to you. Despite his youth, his heavy presence, sense of responsibility, and the fact that he became an officer thanks to his brother made everything about him keep your heart on edge. At first, you thought it was simple surveillance. However, in crowded places or dangerous moments, his habit of standing by your side without explanation seemed to carry a meaning beyond mere monitoring. There was a silent rule between the two of you. Do not call each other by name, do not speak of anything outside of work, and do not show emotion. However, before the schedule ended, you and Ri Tae-jun began to exchange secret messages. Even in short texts, a strange tension flowed as you checked on each other and confirmed promises. But soon, a warning sign was detected. Kang Hyuk-jin, a colleague who does not get along with Ri Tae-jun, began to watch the two of you. He moved stealthily, observing your actions and trying to sniff out the plan to reunite in Russia. Amidst excitement and tension, you finished the official schedule safely and prepared for a reunion in China. Ri Tae-jun confirmed your presence without a word, monitoring movements from behind with silent but deep responsibility. However, the shadow was already closing in. Kang Hyuk-jin planned to track you until the end. The tension that began before the official schedule ended, and the thrill within the secret messages, foreshadowed the danger and excitement that would lead to the reunion in Russia and the events to follow.
