Is Doctor Shin the Next Big Hit? A Deep Dive into Im Sung-han's Latest Drama

[Sports Today reporter Jeong Ye-won] Star writer Lim Seong-han (Phoebe) has struck gold again. With its provocative brain-transfer premise, Doctor Shin has been generating buzz since its premiere.

TV CHOSUN’s new weekend drama Doctor Shin, which debuted on the 14th, is a medical thriller that pits a brilliant surgeon against the limits of the possible and follows a woman whose brain is suddenly damaged as her sense of self slips away. The plot centers on top star Momo (Baek Seo-ra), who falls into a coma after an accident; Jushin (Jeong I-chan), who once loved her; and the strange romances that unfold among the men who orbit her.

The show's premise — swapping brains — attracted attention long before broadcast and earned it the label "the alchemy drama." Curiosity was amplified because this is Lim Seong-han’s first attempt at a medical thriller.

From the outset, Doctor Shin felt unmistakably like a Lim Seong-han production. The blind date between the two leads in episode one delivered moments unlike anything viewers had seen, giving the episode a fresh jolt. Clad in black as if at a European funeral, Momo startled the scene by declaring, "I'm a mama's girl — I'm not charming like a drama character," which injected an oddly tense note into the date. Jushin shot back, "Then I'm an only child, a daddy's boy," and they clinked glasses. Audiences responded with a mix of amusement and bewilderment — asking, "Is this really a blind date?" and noting that the actors were channeling Lim's signature cadence to the letter.

Toward the end of the episode, Ran-hee (Song Ji-in) tries to persuade Jushin with, "All we have to do is transfer the brain to me." The episode closed on a striking image: Momo and Ran-hee on the operating table with their hair being cut, and Jushin, haunted by memories of Momo, picking up the scalpel and beginning the surgery.

Lim holds a singular place in Korea’s television landscape. Through series such as 'See Again and Again', 'The Mermaid', 'The Royal Flower Fairy', 'Dear Heaven', 'Madam of Ahyeon-dong', 'Jewel Bibimbap', 'New Tales of Gisaeng', 'Princess Aurora', 'Apgujeong White Nights', 'Marriage Lyrics, Divorce Composition', and 'Miss Durian', she has built an unmistakable, idiosyncratic body of work. Her offbeat characters and unconventional plots have earned the reputation that "only Lim Seong-han can pull this off," cultivating a dedicated fanbase.

Some dismiss her work as "makjang" — exaggerated melodrama — but her ratings have been resilient. According to Nielsen Korea, her shows posted eye-popping peak ratings: 'See Again and Again' 57.3%, 'The Mermaid' 47.9%, 'Dear Heaven' 44.9%, and 'Princess Aurora' 20.2%. Even as OTT platforms have eroded traditional TV viewing, she still scored solid figures with 'Marriage Lyrics, Divorce Composition II' at 16.6% and 'Miss Durian' at 8.1%.

Another hallmark of Lim’s career is her willingness to cast newcomers in major roles. Actresses who rose to prominence after Lim cast them include Jang Seo-hee in 'The Mermaid', Lee Da-hae in 'The Royal Flower Fairy', Yoon Jung-hee in 'Dear Heaven', Im Soo-hyang in 'New Tales of Gisaeng', Jeon So-min in 'Princess Aurora', and Park Ha-na in 'Apgujeong White Nights'. That pattern demonstrates Lim’s confidence in her own storytelling over star power — and how her writing can elevate an actor’s career.

It has been well over two decades since Lim established herself as a star writer. While many things have changed, her capacity to generate conversation remains steadfast. In an age flooded with new content, attention is already turning to Doctor Shin as viewers tune in to see what singular sensibility Lim will bring to the medical thriller.
