At its core, the series succeeds because of the brilliant chemistry among its lead actors and the distinct personalities they bring to the screen. Understanding who plays who, along with the background of each character, helps clarify why this 2023 JTBC and Netflix drama resonated so deeply with viewers worldwide.
The Legal Titans: Meet the Main Cast
Every great legal drama needs a sharp legal mind at the helm, but this series splits its focus between courtroom battles and deep-seated personal vendettas.
Shin Sung-han (Played by Cho Seung-woo)
Shin Sung-han is the emotional and intellectual anchor of the series. Formerly a music professor and a gifted concert pianist in Germany, he abandons his musical career after a devastating family tragedy claims his sister's life. He returns to South Korea, studies law, and opens a practice dedicated exclusively to divorce cases. Cho Seung-woo brings an eccentric charm to the role, balancing heavy emotional grief with quirky habits like singing along to trot music. He doesn't just litigate; he listens deeply to his clients, using unconventional strategies to win justice.
Lee Seo-jin (Played by Han Hye-jin)
Lee Seo-jin enters the story as a prominent radio DJ and former weather forecaster whose life implodes due to a bitterly contested divorce and a custody battle. After hiring Sung-han, her professional and personal trajectory shifts dramatically. Han Hye-jin delivers an understated performance, portraying a woman fighting to reclaim her dignity and her relationship with her son while enduring intense public scrutiny.
The Supporting Backbone: Friends and Firm Staff
The series thrives on its secondary characters, who inject humor and grounding realism into the narrative. The tight-knit bond between the three middle-school friends forms the beating heart of the show.
Jang Hyeong-geun (Played by Kim Sung-kyun)
As Sung-han's middle-school best friend and the office manager at the law firm, Hyeong-geun handles the day-to-day administrative tasks. Kim Sung-kyun portrays a man dealing with a painful separation from his wife, blending quiet heartbreak with steadfast loyalty to his friends. His character highlights the quiet grief of modern domestic breakups.
Jo Jeong-sik (Played by Jung Moon-sung)
Jeong-sik rounds out the trio of lifelong friends. Running a real estate agency while frequently struggling to pay his rent, Jeong-sik provides much of the show's physical comedy. He is loud, unrefined, but fiercely protective of Sung-han and Hyeong-geun.
Choi Jun (Played by Han Eun-seong)
As a young, ambitious lawyer who joins the firm, Choi Jun brings a fresh wave of energetic comedy. His enthusiastic and slightly dramatic approach to handling cases contrasts sharply with Sung-han's calm, deliberate demeanor.
The Antagonists and Corporate Forces
The overarching plot involves a corrupt corporate power structure and adversarial law firms standing in the way of justice.
Ma Geum-hee (Played by Cha Hwa-yeon)
As a key figure tied to Daenam Electronics, Geum-hee holds critical links to the conspiracy surrounding Sung-han's family history. Cha Hwa-yeon plays this complex role with gravitas, acting as an unexpected internal ally against corrupt corporate interests.
Jin Yeong-ju (Played by Noh Susanna)
Representing the opposing legal and familial forces, Yeong-ju orchestrates obstacles designed to undermine Sung-han both professionally and personally. Her character drives the tension in the latter half of the series.
Common Misconceptions About the Series
Many viewers mistakenly approach this show expecting a fast-paced, high-stakes courtroom thriller akin to American legal procedurals. However, the show operates differently.
- It is not a pure procedural: While cases are resolved episodically, the legal battles serve as a backdrop for emotional healing rather than strict forensic or procedural combat.
- The romance is secondary: Viewers looking for traditional romantic subplots often find that platonic loyalty, self-discovery, and familial redemption take precedence over romantic pairings.
- Pacing is deliberate: The direction favors long, lingering shots and quiet character moments over constant plot twists.
