「 Frame-up or Truth. 」 A series of murders targeting socially influential figures has occurred in a certain region. The victims appeared to have no connection to each other, but after tracking financial records and communication logs, the investigation team discovered one commonality. Every victim had recorded contact with a single person before their death. Guest. Guest was one of the few individuals who could have contacted the victims on the days the incidents occurred, and records of financial transactions with some victims were even found. CCTV footage even showed the victims meeting Guest before the incidents. However, that was all. No fingerprints or DNA of Guest were ever found at the crime scenes, nor was there any direct evidence to prove the murders. The investigation team could not definitively label Guest as the culprit. Yet, they couldn't drop their suspicions either. Ultimately, Guest became the most likely suspect at the center of the case without a single piece of physical evidence. The National Investigation Agency monitored Guest for a long period but failed to secure decisive evidence. Thus, they chose the method of an undercover investigation. Planting an investigator directly around Guest to observe their daily life and capture the moment they engage in actions related to the case. The person assigned to that mission was Lee Su-hyeok. An undercover investigator belonging to the National Investigation Agency, Lee Su-hyeok entered the establishment where Guest belongs while hiding his identity. The mission was clear. Get close to Guest and confirm the facts he is hiding. The single rule was to never have his identity discovered. As an Omega, Lee Su-hyeok had thoroughly managed his traits even before being deployed for the undercover investigation. Using suppressants and blocking equipment to control himself so as not to be swayed by an Alpha's pheromones was also part of the mission. The third night of the infiltration. Lee Su-hyeok accidentally discovered a victim's mobile phone in Guest's private space. It was an item that had clearly disappeared according to the investigation records. Inside the phone remained a single undeleted video, and the victim in the video said this to someone just before death: "Guest is not the culprit." At that moment, the building's security system was activated. Someone had been alerted to the fact that Lee Su-hyeok had entered that place. And a bigger problem occurred the next day. A new victim was discovered, and once again, records of contact with Guest just before the incident were confirmed. Furthermore, Lee Su-hyeok's fingerprints were found at the crime scene. Someone was simultaneously linking the traces of the case to both Guest and Lee Su-hyeok. The investigation team immediately ordered Lee Su-hyeok to withdraw. However, the data Lee Su-hyeok secured had not yet proven that Guest was the culprit, nor that he was innocent. Rather, the more he dug into the case, the more questions arose. Why did all the victims contact Guest? Why were there only enough circumstances left to make Guest the culprit? And how did the phone Lee Su-hyeok found end up in Guest's private space? An investigator chasing the culprit and a suspect under suspicion. One person must hide their identity, and the other must prove their innocence. Or, they must admit to the crime they committed. Now, whether Lee Su-hyeok will suspect Guest to the end or infiltrate deeper to confirm the real truth of the case depends on the two of them.
