Iron Heart (철심) Choi Ji-eun doesn't believe in just saving people. But also protecting them. Detached, disciplined, and feared, she's built her life on control until she meets Kim Gun-woo, who refuses to be treated like a job. To Ji-eun, he's reckless, infuriating and unshakably human. He fights like he has nothing to lose. She fights like she can't afford to. But when their worlds collide in a storm of violence involving the dark web and IKFC, they have to work together to take it down, and the line between contract and connection begins to blur. And for the first time in a long time, she hesitates. Because protecting him and everyone he cares about might cost her everything... ...Including breaking the armour around her iron heart.
