Writer Im Sung-han, better known as Phoebe, is returning with a bold new project, “Doctor Shin,” set to premiere this month.

Often dubbed the “queen of shock twists,” Im is once again embracing an unconventional structure and storyline. This time, she has opted not for a continuation of “Love (ft. Marriage and Divorce)” or “Durian’s Affair,” but for a completely new series. Even the title, “Doctor Shin,” signals an unfamiliar and provocative direction.

Im previously penned a string of hit melodramas known for their extreme plot devices, including “See and See Again,” “Miss Mermaid,” “Lotus Flower Fairy,” “Dear Heaven,” “New Tales of Gisaeng,” “Princess Aurora” and “Apgujeong Midnight Sun.” After declaring a hiatus following the end of “Apgujeong Midnight Sun” in 2015, she returned six years later with TV Chosun’s “Love (ft. Marriage and Divorce)” and followed it with “Durian’s Affair” in 2023.

Her latest comeback, arriving two years after her previous work, has drawn significant attention. While “Durian’s Affair” reflected her signature worldview and provocative settings, it did not achieve the explosive ratings some had anticipated. Still, Im’s name continues to carry weight in the industry. Once hailed as a ratings powerhouse who consistently delivered headline-making dramas, expectations are high that “Doctor Shin” could restore her reputation.

Scheduled to premiere on March 14 on TV Chosun, “Doctor Shin” is a medical thriller that follows a genius doctor who challenges the realm of the divine and a woman who loses her soul after her brain is suddenly damaged. The series marks Im’s first foray into the medical genre. Having built her own narrative grammar across family sagas, melodramas filled with extreme twists, reincarnation themes and spirit possession, viewers are watching closely to see how she will reinterpret the relatively realistic subject of medicine.

The most shocking element of the new drama is the physical brain swap between a mother and daughter. It is not a simple case of amnesia or possession. The premise involves literally exchanging their brains. The idea of replacing the brain, which governs identity, memory and the soul, simultaneously touches on science, ethics and familial love. While the premise risks being consumed as mere sensationalism, it also has the potential to raise deeper questions about human existence.

For Im, shock value has long been inseparable from her storytelling. In “See and See Again,” “Miss Mermaid” and “Dear Heaven,” extreme family conflicts drove the narrative. In the “Love (ft. Marriage and Divorce)” series, she boldly incorporated infidelity, death and possession, sustaining buzz throughout its run. However, critics said that as the series progressed, excessive plot devices undermined its overall cohesion. “New Tales of Gisaeng” featured possession, “Princess Aurora” explored out-of-body experiences and “Durian’s Affair” ventured into time-transcending fantasy.

“Durian’s Affair” itself was built on an unusual premise, blending time slip elements with the modern-day adaptation of characters from the Joseon era. Despite its originality, critics said it fell short in constructing a fully convincing narrative. The shock factor was present, but the emotional arcs and plausibility did not always support the story. As such, “Doctor Shin” may need to focus more on detail and narrative logic rather than simply escalating its level of sensationalism.

Given the nature of a medical thriller, any weak medical foundation could break immersion. At the same time, maintaining suspense requires tightly woven character choices and conflicts. Whether Im’s distinctive dialogue style and character dynamics can create synergy with the genre is another key point of interest. The combination could feel discordant, but it also holds the possibility of a fresh reinterpretation.

Another notable aspect is the casting of newcomers. Im has previously drawn attention for bold casting choices, and the lead roles in “Doctor Shin” are played by relatively unfamiliar faces, including Jung Yi-chan and Baek Seo. By spotlighting new actors, she appears to be aiming to enhance the series’ freshness.

The unprecedented premise of a mother-daughter brain swap is undeniably a strong hook in terms of buzz. However, it must function as a necessary narrative device rather than shock for shock’s sake. Industry observers are now asking whether Im can once again reclaim her title as the “queen of ratings.”
