The Regressed Doctor Just Wanted to Live Quietly

Dr. Jinhyeok Lee is a brilliant surgeon whose skill in the operating room is second to none. Calm, uncompromising, and exceptionally talented, he has dedicated his entire life to medicine. But his relentless pursuit of perfection comes at a heavy cost, leaving him distant from his family and the people who care about him. By the time he realizes everything he has sacrificed—including the chance to be with his mother in her final moments—it is already too late.

Or so he believes.

Jinhyeok suddenly awakens 27 years in the past, armed with all the memories and experience of his previous life. Given an extraordinary second chance, he vows not only to become an even better doctor but also to protect the people he once neglected.

Yet rewriting the past is far from simple. Old rivals return, new challenges emerge, and countless patients place their lives in his hands. As he walks the line between saving lives and changing fate, Jinhyeok is determined to uphold the principle that guides every true physician: Primum non nocere — First, do no harm.
