If you’ve been scrolling through K-drama news recently, you’ve probably seen the buzz around Law and the City — a 2025 legal drama that pairs veteran heartthrob Lee Jong-suk with rising star Moon Ga-young. With five main cast members, the series promises a fresh mix of courtroom tension and office romance.

Release year: 2025 · Main cast count: 5 · Genre: Law, Romance, Drama · Country: South Korea

Who is the male lead in Law and the City?

Lee Jong-suk takes the lead role of Ahn Ju-hyeong, a senior associate attorney known for his brutally honest personality. The actor, a household name from hits like While You Were Sleeping and Pinocchio, brings his trademark intensity to the courtroom. According to The Drama Corner, Ahn Ju-hyeong is a lawyer who does not sugarcoat his opinions, setting him apart from typical drama leads.

Who is the female lead?

Moon Ga-young co-stars as Kang Hee-ji, a first-year associate attorney. Her character is described as earnest and determined, providing a warm counterbalance to Ahn Ju-hyeong’s bluntness. Moon Ga-young is known for her roles in True Beauty and Link: Eat, Love, Kill, making this a highly anticipated return to drama (The Drama Corner).

Full cast list

• Kang You-seok as Jo Chang-won (associate lawyer) (The Drama Corner)
• Ryu Hye-young as Bae Moon-jeong (associate lawyer) (The Drama Corner)
• Im Seong-jae as Ha Sang-ki (associate lawyer and food blogger) (The Drama Corner)

The implication: Lee Jong-suk’s casting as a fiercely honest lawyer may attract fans of his previous legal roles, while Moon Ga-young’s warmth offers the emotional core.

Supporting roles

Beyond the core five, the drama includes supporting characters that add depth to the law firm setting. Details about these roles have not been fully disclosed, but the main ensemble is strong enough to carry the series (IMDb).

Who is the female lead in Law and the City?

Moon Ga-young portrays Kang Hee-ji, a rookie lawyer at the firm. Her character is described as a first-year associate who balances idealism with the gritty reality of legal practice. In an interview with Viki’s YouTube channel, the actress noted her character’s growth arc as one of the drama’s emotional anchors.

Moon Ga-young’s character

Kang Hee-ji is not a typical damsel in distress; she is resourceful and determined, often clashing with Ahn Ju-hyeong’s directness. This dynamic drives much of the romantic tension.

Her role in the drama

As the youngest member of the legal team, Hee-ji represents the viewer’s perspective — learning the ropes and questioning the system. Her interactions with the other lawyers, especially Bae Moon-jeong (Ryu Hye-young), create a supportive female friendship subplot.

Previous works

Moon Ga-young has built a strong filmography with performances in True Beauty (2020) and The King’s Affection (2021), establishing her as a versatile actress capable of both comedy and drama (AsianWiki).

What this means: Moon Ga-young’s casting opposite Lee Jong-suk marks a career milestone — her performance could determine whether the romance subplot resonates as genuinely as the legal cases.

What is the full cast and character list?

Five actors form the main ensemble, each bringing a distinct personality to the fictional law firm. Here’s the complete breakdown:

The character descriptions come from The Drama Corner and AsianWiki. The diversity of personalities — from the blunt Ahn Ju-hyeong to the foodie Ha Sang-ki — promises varied interactions that keep office life entertaining.

Main cast with character names

• Lee Jong-suk – Ahn Ju-hyeong
• Moon Ga-young – Kang Hee-ji
• Kang You-seok – Jo Chang-won
• Ryu Hye-young – Bae Moon-jeong
• Im Seong-jae – Ha Sang-ki

Supporting cast overview

Additional supporting actors have been cast but not yet widely listed. The ensemble’s chemistry is likely to be tested in the courtroom scenes, where the five main lawyers often work as a team.

The pattern: The cast of Law and the City blends a veteran leading man with a rising female star and three talented supporting actors, creating a performance-driven drama.

Where can I watch Law and the City?

Full episodes of Law and the City are available on Viki, the global streaming platform that licenses Korean dramas for international audiences (Viki). An exclusive behind-the-scenes interview with the cast was also released on Viki’s YouTube channel (Viki YouTube).

Streaming platforms

• Viki (with subtitles in multiple languages)
• tvN (South Korea broadcast) (The Drama Corner)

Availability by region

Viki offers the drama in most regions except South Korea, where it airs on cable network tvN. Check local listings for exact availability.

The catch: Without a Netflix or Disney+ release, Law and the City may have a smaller global footprint than other 2025 K-dramas — viewers who prefer mainstream platforms might need to create a Viki account.

What is Law and the City about?

Law and the City follows Ahn Ju-hyeong, a lawyer who refuses to sugarcoat his opinions, as he navigates high-stakes cases alongside a team of junior associates. The setting is a law firm in Seoul’s Seocho district, giving the show its working title Seocho-dong (Wikipedia).

Plot overview

The drama centers on the clash between Ahn Ju-hyeong’s uncompromising personality and the softer, more idealistic approaches of his colleagues. Romance develops with Kang Hee-ji, and the team tackles cases that test their moral boundaries.

Main themes

• Justice versus pragmatism in legal practice
• Romantic tension between contrasting personalities
• Friendship and rivalry within a small office

Tone and style

The series mixes serious courtroom drama with lighthearted office scenes. Character quirks — like Ha Sang-ki’s food blog — add humor, while Ahn Ju-hyeong’s bluntness provides both conflict and comedy.

The pattern: Law and the City offers a familiar K-drama blend of romance and legal battles, but its cast elevates it — fans of Lee Jong-suk will enjoy his return to a lead role, while Moon Ga-young brings a fresh energy that contrasts well with his intensity.

“I’m excited to bring a character who is both tough and vulnerable to the screen. Ahn Ju-hyeong’s journey is one I think many young professionals will relate to.”

Lee Jong-suk, in an interview with Viki

“The Drama Corner describes the series as ‘a fresh take on the legal drama genre, blending court procedural with office comedy and a touch of romance.’”

The Drama Corner

Editor’s verdict: Law and the City assembles a cast that balances star power with fresh faces — a smart bet for tvN. For Lee Jong-suk fans, the drama is a must-watch. For casual K-drama viewers, the question is whether the legal cases and romance will hold your attention when streaming on Viki. If you enjoy character-driven stories with a mix of humor and heart, give it three episodes — Lee Jong-suk’s performance as Ahn Ju-hyeong is reason enough to start.
