## Premise

Do Ji-ui is a brilliant young plastic surgeon aiming for a top career at one of South Korea's most prestigious universities, but he is emotionally closed off and burdened by a trauma connected to the sea. As part of his military service, privileged medical students can serve as public health doctors instead of active duty, and Ji-ui is unexpectedly assigned to Pyeondongdo, an isolated island that no one wants, for a year.<sup>[1](https://www.disneyplus.com/en-sg/explore/articles/doctor-on-the-edge)</sup><sup> • </sup><sup>[3](https://www.justwatch.com/us/tv-show/doctor-on-the-edge)</sup> He sees the sea-surrounded island as a giant cage and his goal is simply to endure quietly and escape.<sup>[1](https://www.disneyplus.com/en-sg/explore/articles/doctor-on-the-edge)</sup><sup> • </sup><sup>[2](https://catsky.tistory.com/entry/Doctor-on-the-Edge)</sup>

There he meets Yook Ha-ri, a nurse at the island's public health branch who has come from the city for her own reasons and hides her secrets behind a cheerful smile. Between overfamiliar residents, swarms of insects, and life-or-death emergencies, the two discover each other's past wounds and gradually open up.<sup>[1](https://www.disneyplus.com/en-sg/explore/articles/doctor-on-the-edge)</sup><sup> • </sup><sup>[2](https://catsky.tistory.com/entry/Doctor-on-the-Edge)</sup> The series places a small public health center and the island community at the center instead of a major hospital, narrowing the scale of the medical genre while concentrating on the characters.<sup>[5](https://issuetalk.co.kr/en/k-drama/doctor-on-the-edge-week-two-will-decide-the-pyeondongdo-effect)</sup>

## Ratings and reception

Nielsen Korea's figures for paid households showed the opening episode drawing 4.0% across the nation, 3.6% within the Seoul metropolitan area, and topping out at a 4.5% rating for a single minute, making it, by reported numbers, the strongest premiere yet for an ENA Monday-Tuesday drama.<sup>[5](https://issuetalk.co.kr/en/k-drama/doctor-on-the-edge-week-two-will-decide-the-pyeondongdo-effect)</sup> The second episode approached 5%.<sup>[2](https://catsky.tistory.com/entry/Doctor-on-the-Edge)</sup> The series followed *Strawman*, which had climbed from 2.9% to an 8.1% finale in the same slot, so the drama's task was framed as protecting a high starting point rather than building interest from low numbers.<sup>[5](https://issuetalk.co.kr/en/k-drama/doctor-on-the-edge-week-two-will-decide-the-pyeondongdo-effect)</sup>
