Trivia, insights & behind the scenes
Lee Joon-gi performed most of his own stunts, including the famous bridge jump sequence that took six takes.
The drama aired during a wave of 'dad hero' Korean thrillers, but stood out for its biological clock premise—rarely do action heroes race against their child's marrow transplant window. Soo-jin's 'ajusshi' becoming 'Dad' mirrors Korea's complex adoption and single-parent stigma.
