5 Most-Watched K-Dramas of March 2026, One Title Surged Past 10 Percent

March has become a strong month for Korean drama fans, especially for viewers who like mystery, thriller, and romance titles with high-stakes storytelling. Based on the latest Nielsen Korea ratings and the current streaming lineup, five dramas stand out as the most talked-about and widely watched choices.

These titles gained attention for different reasons, from strong debuts and steady momentum to a final episode that ended on a high note. The group also reflects broader viewing trends, with legal thrillers, emotional romance, and suspense-heavy plots driving consistent interest across major platforms.

1. Phantom Lawyer

Among all the titles on the list, Phantom Lawyer emerged as the clear leader. The legal fantasy drama reached a peak national rating of 10 percent on March 21, making it the highest-rated miniseries in its weekly slot.

The story follows Shin Yi-rang, played by Yoo Yeon-seok, a timid and awkward lawyer who unexpectedly gains the ability to see ghosts after moving to a new office. He teams up with elite lawyer Han Na-hyun, played by Esom, who initially doubts his supernatural claims.

As they begin handling unresolved cases linked to restless spirits, the story builds both emotional tension and mystery. The combination of genre elements appears to be one reason the drama attracted a broad audience, and it is available on Netflix, Viki, and Viu.

2. Siren’s Kiss

Siren’s Kiss brought together romance and suspense in a way that helped it secure strong early attention. The drama opened on March 2 with its highest rating at 5.5 percent and later posted 4.0 percent for its eighth episode on March 24.

The series centers on Cha Woo-seok, played by Wi Ha-jun, an investigator tracking an insurance fraud scheme tied to a series of unexplained deaths. His investigation leads him to Han Seol-ah, portrayed by Park Min-young, a woman believed to be at the heart of the entire case.

The deeper Woo-seok goes into the mystery, the more dangerous the situation becomes, especially as his interest in Han Seol-ah blurs the line between professional duty and personal risk. The drama streams on Prime Video and has gained attention for combining a crime plot with emotional and psychological tension.

3. Honour

Honour ended its run with strong audience support and solid critical momentum. The legal mystery thriller aired its final episode on March 10 and recorded a personal best with a nationwide average rating of 4.7 percent.

The drama follows three longtime friends, Yoon Ra-young, Kang Shin-jae, and Hwang Hyun-jin, who have known each other for about 20 years. They first met in their twenties as students and now work together as lawyers at L&J Law Firm, which focuses on defending women who have survived crimes.

A secret from two decades earlier resurfaces and disrupts their lives, forcing the three women to stand together again. The series stood out for its themes of solidarity, resilience, and unfinished history, and it is available on Viu.

4. The Practical Guide to Love

The Practical Guide to Love showed that a romance drama can still hold steady in a crowded viewing market. Near the final week of its run, the series reached a rating of 4.4 percent on March 29, which reflected stable viewer interest rather than a sudden spike.

The drama follows Lee Ui-young, played by Han Ji-min, a woman in her 30s who works as an assistant manager in a hotel purchasing team. She is skilled at work and trusted by people around her, but her private life has not gone as well.

To change that, she decides to pursue a relationship without commitment and goes on blind dates, where she meets two very different men, Song Tae-seob and Shin Ji-soo. Song Tae-seob, played by Park Sung-hoon, is gentle in appearance but firm in personality, while Shin Ji-soo, played by Lee Ki-taek, starts out wanting freedom but changes gradually because of Ui-young.

The show premiered on HBO Max on February 28 and has drawn viewers who prefer romance stories with adult characters and realistic emotional conflict.

5. Climax

Climax is the newest title on the list, but it has already shown clear upward momentum. The drama, starring Ju Ji-hoon and Ha Ji-won, reached its highest rating so far at 3.9 percent with its third episode on March 23.

The plot follows a violent struggle for power involving a prosecutor who joins a cartel to rise to the top in Korea and the people around him. Ju Ji-hoon plays Bang Tae-seob, a prosecutor who becomes a star after marrying top actress Chu Sang-a, played by Ha Ji-won.

The story widens through several key figures, including Nana as a secret informant who holds crucial information and Cha Joo-young as a powerful woman fighting for succession inside WR Group. With corporate conflict, political ambition, and hidden alliances, the series leans heavily into the kind of prestige thriller that often performs well on streaming platforms.

Why these dramas are drawing attention

Taken together, the five titles show a clear pattern in current Korean drama viewing habits. Mystery and thriller-heavy stories continue to dominate, but romance still matters when it is paired with layered characters and emotional stakes.

A simple ranking of the most notable titles based on recent ratings and attention can help readers compare them quickly:

The data also suggests that audiences are responding to familiar themes presented in fresh ways. Supernatural legal cases, insurance fraud investigations, long-hidden secrets, adult romance, and power struggles inside elite institutions all remain highly clickable storylines.

Another notable point is the strength of the cast lineup across the five dramas. Actors such as Yoo Yeon-seok, Park Min-young, Ju Ji-hoon, Ha Ji-won, and Han Ji-min bring built-in viewer interest, while the mix of seasoned and newer performances helps each project reach different audience segments.

Streaming availability also plays a major role in visibility, since these dramas are spread across Netflix, Viki, Viu, Prime Video, and HBO Max. That wide distribution gives them a larger path to discovery, especially for international viewers searching for currently trending Korean series.

For viewers choosing what to watch next, Phantom Lawyer stands out for its rating performance and unusual premise, while Siren’s Kiss and Climax offer darker, more suspense-driven options. Honour and The Practical Guide to Love provide a strong contrast through emotional depth and relationship-focused storytelling, making the five dramas a balanced snapshot of what is resonating most with audiences right now.
