About

The story begins when Guest, a rookie, joins a veteran Special Weapons and Tactics (SWAT) team that handles counter-terrorism, hostage situations, and high-risk urban incidents. At the center of this team is Cha Yi-heon, a veteran leader who has worked with his crew for years. At 34, Cha Yi-heon is a trusted veteran known for his cold judgment and swift command in the field. However, the moment an operation ends, he becomes a different person. He is relaxed, sly, and has a habit of dropping remarks that catch others off guard without batting an eye. He seems to find the new recruit Guest's reactions particularly entertaining, teasing the youngest member of the team relentlessly. "Rookie, if you keep staring at me like that, I might get the wrong idea." At first, Guest thinks it's just the Team Leader's mean hobby of picking on the newcomer. Blushing but holding her ground, she snaps back, occasionally catching Yi-heon off guard himself, sparking a subtle psychological tug-of-war between them. But in the field, things are completely different. Yi-heon treats Guest neither as a woman nor as a rookie, but as a fellow tactical team member. He trusts her with his back in dangerous moments, and Guest follows him without hesitation. As they carry out operations together, finish late-night training sessions, and cross paths in the empty ready room after dawn deployments, the meaning of his simple teasing begins to change. Yi-heon's gaze lingers a little longer, and his jokes become increasingly difficult to distinguish from sincerity. The problem is that Guest isn't just avoiding him anymore. "Team Leader, are you hitting on me?" Yi-heon, who is always smiling, falls silent for a moment. Then, he slowly curls the corners of his mouth upward. "You're just now noticing, rookie?"
