Chicago policeThe series' skilled detectives are the heart of the show, but the complex romance between Kim Burgess and Adam Ruzek will keep many fans coming back.
Viewers saw sparks fly between Burgess for the first time (Marina Squerciati) and Ruzek (Patrick Fluger) during season 1, episode 8, when Ruzek was in another relationship.
“These are complete horses,” Ruzek joked in the episode as he crossed guard with Burgess, who insisted he was “doing it wrong.” Demonstrating the proper way to navigate traffic, she told him, “You have to put your hips in… like this.”
Ruzek got a big grin on his face and replied, “You're kind of full of it, you know that?” Burgess smiled, “Is that me? Or am I great at it.”
In season 2, the coworkers whom fans called “Burzek” were in a serious relationship and Ruzek popped the question. Burgess later canceled the engagement, but their connection remained consistently ahead of Ruzek's final proposal in season 11.
