In "Flex X Cop 2," Ahn Bo-hyun and Jung Eun-chae track down a brutal romance murder mystery hidden behind the luxurious facade of a five-star hotel.

Ahead of its Episode 5 broadcast, the SBS Friday-Saturday drama "Flex X Cop 2" (written by Kim Ba-da, directed by Kim Jae-hong), which is maintaining a steep upward trend with a peak viewership rating of 7.4%, released stills capturing Jin Yi-soo (Ahn Bo-hyun) and Joo Hye-ra (Jung Eun-chae) arriving at a new crime scene.

The stage for this case is the upscale "Rosebud Hotel." The investigation begins when a hotel employee is found dead in the middle of a guest room. The full story behind the tragedy that occurred on White Day—questioning why a hotelier died in an empty guest room meant for guests—is set to be unveiled step by step.

Amidst this, an unexpected person who will serve as a crucial clue to the investigation is spotted at the scene: a suspicious guest named Kang Chunsik (played by Lee Seok), wearing sleeping pajamas and an eye mask. As the only son of a food company owner and someone connected to Jin Yi-soo through chaebol family circles, Kang Chunsik shows familiarity by calling Jin Yi-soo "hyung" the moment he sees him, despite being a suspect.

While the quirky "older brother-younger brother" chemistry between the two, which defies age and visual differences, brings laughter, Jin Yi-soo is expected to continue his signature cheeky interrogation without cutting any slack, even in front of his "younger acquaintance."

Episode 5 of "Flex X Cop 2," which is drawing high expectations for its combination of comedic investigative drama and tense makjang romance elements, airs tonight at 9:50 PM.
