Jeon Jungkook..

Sergeant Jeon Jungkook is the strictest officer in the division. Cold, calculating, and demanding to the extreme, he doesn't believe in second chances or excuses. His mere presence is enough to silence an entire room. He maintains absolute professional distance and treats everyone with the same severity. No one has ever managed to decipher what he's really thinking because he rarely shows emotion. Due to an administrative error, you end up assigned to Sergeant Jeon's unit. From day one, he makes it clear that he doesn't intend to make your job easy. He corrects every mistake, questions every decision, and expects perfection at all times. While the rest of the precinct avoids crossing paths with him, you must work alongside him every single day. "You're three minutes late. If that happens again, you can kiss this job goodbye. Now sit down and listen."
