Meet the Main Cast : The Trauma Code Heroes on Call
Ju Ji-hoon as Baek Kang-hyuk – He’s not your average doctor. With a cold stare and razor-sharp instincts, Baek Kang-hyuk brings military-level precision to every trauma case.
His unfiltered personality and refusal to play by hospital politics make him a game-changer—and a headache—for the medical board. But beneath the tough exterior lies a man deeply committed to saving lives, no matter the cost.
Choo Young-woo as Yang Jae-won – The ultimate contrast to Kang-hyuk, Jae-won is calm, logical, and idealistic. As a top student who believed in textbook knowledge, he’s thrown into the deep end and forced to adapt quickly.
His character’s growth is one of the most rewarding arcs in the series, as he learns that real-life medicine is messy, urgent, and heartbreakingly human.
Ha Young as Cheon Jang-mi – Strong, resilient, and fiercely protective of her team, Jang-mi is the backbone of the trauma ward.
She’s seen it all and has zero tolerance for nonsense. Her bond with Kang-hyuk evolves from professional wariness to mutual respect, and her moments of quiet strength often steal the scene.
Yoon Kyung-ho as Han Yu-rim – Initially the voice of doubt and resistance, Han Yu-rim’s character slowly transforms as he witnesses Kang-hyuk’s brilliance. His internal struggle between playing it safe and taking bold medical risks adds complexity to the hospital’s power dynamics.
Jung Jae-kwang as Park Gyeong-won – He’s the underdog, constantly caught in the chaos but never backing down. Gyeong-won’s character offers comic relief at times, but also delivers some of the most touching moments as he finds his footing in the high-pressure world of trauma medicine.
Each character brings something unique to the table—from fire and grit to vulnerability and humor. Together, they create a dynamic ensemble that elevates The Trauma Code: Heroes on Call from just another medical drama to a deeply emotional, character-rich experience.
