In "Flex x Cop," Ahn Bo Hyun and Kwak Si Yang are polar opposites, but close and endearing brothers

Ahn Bo Hyun and Kwak Si Yang will have wonderful chemistry as brothers in the upcoming SBS drama "Flex x Cop"!. "Flex x Cop" follows Jin Yi Soo (Ahn Bo Hyun), an immature third-generation chaebol who becomes a detective as a result of his wealthy upbringing, and Lee Kang Hyun (Park Ji Hyun), a hardworking senior detective who is also the first female unit head in the Homicide Department. Kwak Si Yang plays Jin Seung Joo, Jin Yi Soo's older brother and the vice president of Hansoo Group. Jin Seung Joo not only helps Jin Yi Soo transition into a detective and join Lee Kang Hyun's team in the Homicide Department, but he is also Jin Yi Soo's best friend. Despite the fact that they are brothers, the two have very different personalities in the recently revealed photos. Despite the bright brightness, Jin Yi Soo looks to be reclining on his bed in casual sleepwear, with a bandage on his nose that gently betrays his mischievous character. On the contrary, Jin Seung Joo is immaculately dressed in a well-tailored suit, exuding the impression of a model citizen. The diametrically opposing personalities of these two brothers provide suspense to their family dynamic and storyline. The subsequent stills reveal insight into the brothers' relationship. Jin Seung Joo, who is used to coping with Jin Yi Soo's rebellious conduct, greets him warmly and grins proudly when he sees Jin Yi Soo in a sharp police uniform, much like a pleased father seeing their child perform at a school event. Catch the two brothers' adorable connection in "Flex x Cop," which premieres January 26, 2024, at 10 p.m. KST.
