K-dramas have gained massive global popularity, but not every great series receives the attention it deserves. Many shows deliver strong storytelling, memorable performances, and unique concepts, yet remain overlooked due to limited hype.
This list highlights 10 underrated K-dramas that stand out for their quality and lasting impact. If you enjoy meaningful stories beyond mainstream trends, these dramas are worth your time. Let’s explore.
Key Takeaways( Quick Overview)
- Not all high-quality K-dramas become worldwide hits. Mostly, the exceptional series are still underrated because of limited promotions or slow-burn writing.
- The production of these dramas makes the main focus on strong scripts, realistic feelings, and character’s interior rather than visual attractions or popular trends.
- Psychological thriller, slice of life, and melodrama are among the genres that typically last longer than the trend-based romantic comedies.
- Even though international hype remained low, several dramas in this list received critical acclaim in South Korea, including awards and nominations.
- Those K-dramas that are less talked about often contain the boldest storytelling choices which the mainstream shows frequently escape from.
- The viewers who are after the smart and meaningful content will probably get a more profound connection with these series.
- These dramas are perfect for binge-watching because they provide constant narrative tension as their main technique, not cliffhanger tricks.
1. The Psychopath Diary (2019)
Genre: Thriller, Comedy
Starring: Yoon Shi-yoon, Jung In-sun
“The Psychopath Diary” proves that dark humor and crime thrillers can coexist without losing balance.
The story follows Yook Dong-sik, a timid office worker who accidentally witnesses a murder. After a sudden accident, he loses his memory and wakes up believing he is a serial killer—because he finds the killer’s diary in his possession.
The brilliance of this drama lies in its contrast. Dong-sik tries to act like a psychopath while remaining painfully kind and awkward. The show uses comedy to highlight human fear and identity, not to trivialize violence.
Despite solid ratings in South Korea and praise for Yoon Shi-yoon’s performance, the series never gained strong international traction. That makes it one of the most overlooked K-dramas in the thriller-comedy genre.
2. Beyond Evil (2021)
Genre: Psychological Thriller
Starring: Shin Ha-kyun, Yeo Jin-goo
“Beyond Evil” does not rush its story—and that patience is its greatest strength.
Set in a seemingly quiet town, the drama explores a cold case murder that resurfaces after many years. As new crimes unfold, trust erodes, and everyone becomes suspicious.
The series focuses on moral ambiguity rather than clear heroes and villains. Shin Ha-kyun’s performance earned critical acclaim and major awards, including recognition from South Korea’s prestigious Baeksang Arts Awards.
Internationally, many viewers missed this drama due to its slow-burn nature. However, for fans of intelligent thrillers, “Beyond Evil” delivers layered writing and psychological tension that stays consistent until the end.
3. Flower of Evil (2020)
Genre: Thriller, Romance
Starring: Lee Joon-gi, Moon Chae-won
“Flower of Evil” blends romance with psychological suspense in a way that feels both emotional and unsettling.
The story centers on Do Hyun-soo, a man hiding a dark past while living a seemingly perfect life with his detective wife and daughter. When a series of murders connects to his childhood trauma, his carefully built world begins to crack.
Lee Joon-gi’s portrayal of emotional suppression and fear stands out as one of his most complex roles. While the drama performed well domestically, it never reached the global popularity of other thrillers released around the same time.
That gap in recognition makes it an underrated gem for viewers who enjoy character-driven suspense with emotional depth.
4. Miss Night and Day (2024)
Genre: Mystery, Comedy, Romance
Starring: Jung Eun-ji, Choi Jin-hyuk
“Miss Night and Day” introduces a playful concept with surprising emotional weight.
The protagonist, Lee Mi-ji, lives under a strange curse. During the day, she turns into an elderly woman. At night, she returns to her younger self. This condition unexpectedly helps her land a job at a prosecutor’s office.
While the premise sounds comedic, the drama carefully blends mystery, romance, and personal growth. The humor feels situational rather than forced, and the emotional beats remain grounded.
Although it aired recently, the drama did not receive strong international marketing. As a result, many viewers missed one of the most creative genre blends of 2024.
5. Behind Your Touch (2023)
Genre: Comedy, Crime
Starring: Han Ji-min, Lee Min-ki
“Behind Your Touch” embraces absurdity—and then surprises you with substance.
Han Ji-min plays a veterinarian who gains psychic powers after an accident. There is one unusual condition: she must touch people’s backsides to see their memories. Yes, it sounds ridiculous, and the drama knows it.
What keeps this series engaging is its self-awareness. The comedy feels intentional, not accidental. Beneath the humor lies a well-structured crime mystery involving a serial killer in a small town.
Despite strong performances and positive viewer feedback, the drama remained underappreciated outside Korea.
6. My Liberation Notes (2022)
Genre: Slice of Life, Drama
Starring: Kim Ji-won, Son Suk-ku
“My Liberation Notes” speaks quietly, but its message resonates deeply.
The drama explores the lives of three siblings trapped in monotonous routines, emotional isolation, and unspoken dissatisfaction. It does not rely on dramatic twists or loud conflicts.
Instead, it focuses on everyday exhaustion, loneliness, and the human desire to feel understood. Son Suk-ku’s character became widely discussed in Korea for his minimal yet impactful dialogue.
While critics praised the series for realism, many international viewers skipped it due to its slow pacing. That choice often comes with regret after discovering its emotional honesty.
7. Lost (2021)
Genre: Melodrama
Starring: Jeon Do-yeon, Ryu Jun-yeol
“Lost” portrays emotional emptiness with rare sensitivity.
The drama follows two individuals facing personal failure, grief, and quiet despair. Instead of offering easy hope, the story allows characters to sit with their pain.
Jeon Do-yeon delivers a restrained performance that avoids melodrama, despite the genre label. The show earned critical respect but struggled to attract mainstream audiences.
For viewers who appreciate mature storytelling and introspective themes, “Lost” remains one of the most underrated Korean dramas of recent years.
8. The Smile Has Left Your Eyes (2018)
Genre: Romance, Thriller
Starring: Seo In-guk, Jung So-min
This drama challenges traditional romance narratives.
Seo In-guk plays a morally ambiguous character whose past remains shrouded in mystery. As love develops, the story gradually reveals emotional trauma and hidden darkness.
The series received mixed reactions during its airing due to its heavy themes. However, over time, viewers began to appreciate its tragic storytelling and emotional risks.
It may not suit everyone, but its lasting impact makes it unforgettable for the right audience.
9. Nobody Knows (2020)
Genre: Crime, Mystery
Starring: Kim Seo-hyung
“Nobody Knows” stands out for its emotional restraint.
The drama follows a detective haunted by an unsolved serial murder from her past. Years later, a new case emerges, connecting deeply with a student she cares about.
Instead of focusing solely on crime, the story highlights trauma, responsibility, and quiet compassion. Kim Seo-hyung’s performance received strong critical praise.
Despite this, the drama remained under-discussed internationally, placing it firmly among underrated K-dramas.
10. Misaeng: Incomplete Life (2014)
Genre: Workplace, Slice of Life
Starring: Im Si-wan
“Misaeng” captures the harsh reality of office life with honesty and empathy.
The drama follows Jang Geu-rae, a former baduk player struggling to survive corporate culture as a contract employee. There are no shortcuts, no unrealistic victories, and no dramatic villains.
Instead, the story highlights quiet resilience, teamwork, and professional insecurity. The series earned high praise from industry professionals and office workers alike.
While popular in Korea, newer international audiences often overlook it, despite its timeless relevance.

A Personal Note as a Viewer
As someone who has watched K-dramas for years, underrated series often leave the strongest impression on me. They do not chase trends or rely on viral moments. Instead, they take their time, trusting the story and the audience to meet somewhere in the middle.
What I appreciate most about these dramas is their honesty. They are not afraid of silence, emotional discomfort, or slow progression. Characters feel flawed, sometimes frustrating, but always human. That realism makes their journeys feel personal, not scripted for applause.
Some of these dramas pull you in with psychological tension, others with quiet emotional warmth. A few may not hit you immediately, but they stay with you long after the final episode. You find yourself thinking about a scene, a line of dialogue, or a character’s choice days later—and that kind of impact is rare.
Underrated K-dramas remind me why I started watching Korean storytelling in the first place. Not for hype or numbers, but for stories that understand loneliness, growth, fear, and connection without overexplaining them. They may not be loud, but they mean something—and sometimes, that matters far more.
