This is the setting for the Seoul Central Police Station, where On Joon-young (Seo Kang-joon) and the rest of Violent Crimes Team 3 are based at in The Third Charm / The 3rd Charm (제3의 매력) (JTBC, 2018). In episode 5, Lee Young-jae follows Joon-young back to the station after she finds out why he hadn’t been picking up her calls. She finds his jealous outburst endearing (or “cute”, in her words), and kisses him in front of the station. This melts the pouty Joon-young slightly, and he offers to give her a ride.
