Nana, Kim Dan and Jung Gun Joo Confirmed for Netflix’s New Mystery K-Drama Ma Teresa

Netflix is bringing together Nana, Kim Dan, and Jung Gun Joo for a new mystery thriller series titled Ma Teresa.

The upcoming K-drama will follow a cold-blooded criminal psychologist and professor who becomes involved in a series of unsolved murder cases. As she investigates the crimes alongside her mysterious teaching assistant and longtime prosecutor friend, buried secrets, past trauma, and unexpected emotions begin to emerge.

With a story combining murder investigations, psychological tension, hidden secrets, and complicated relationships, Ma Teresa is set to offer a darker side of Korean drama storytelling.

Nana Leads Ma Teresa as a Criminal Psychologist

Nana will take on the titular role of Ma Teresa, a criminal psychologist and professor known for her cold and intense personality.

Teresa is brought in as a consultant when a series of unsolved murder cases captures widespread public attention. Rather than simply analyzing the evidence from a distance, she personally confronts and interrogates criminals while following the clues surrounding each case.

However, Teresa’s interest in these investigations is connected to more than professional curiosity.

She carries trauma from her past and has been pursuing the truth surrounding it for a long time. As she gets closer to uncovering the answers she has been searching for, emotions she has kept buried begin to surface.

Nana is expected to portray both Teresa’s intimidating professional side and her complicated emotional world.

Kim Dan Plays Teresa’s Mysterious Assistant

Rising actor Kim Dan will play Park Seol, Teresa’s teaching assistant.

Park Seol has remained by Teresa’s side for a long time and assists her as she investigates the murder cases. Although he appears innocent and harmless on the surface, he is hiding secrets of his own.

His character is also hoping to gain Teresa’s attention, adding a personal element to their professional relationship.

As the investigation progresses, Park Seol’s suppressed emotions and unpredictable nature are expected to become increasingly important to the story.

The character could prove to be one of the drama’s biggest mysteries as viewers gradually discover what lies behind his seemingly innocent smile.

Jung Gun Joo Takes on the Role of a Prosecutor

Jung Gun Joo will portray Yoo Ah Ram, a prosecutor and Teresa’s longtime friend.

Ah Ram works alongside Teresa and helps her with the murder investigations. However, he is not entirely comfortable with Park Seol’s constant presence around her.

His suspicion toward Park Seol adds another layer of tension to the relationships between the three central characters.

At the same time, Ah Ram shares a long history with Teresa, giving their relationship an emotional depth that could become increasingly important as the story unfolds.

Jung Gun Joo is expected to bring out the character’s subtle emotions and delicate inner conflicts.

A Murder Mystery Filled With Hidden Secrets

At the heart of Ma Teresa are a series of unsolved murder cases that have attracted significant public attention.

Teresa uses her expertise as a criminal psychologist to examine the cases and uncover clues that could lead to the truth.

But the deeper she investigates, the more the cases begin to connect with her own unresolved past.

Her investigation will also bring her closer to Park Seol and Yoo Ah Ram, whose own emotions and secrets complicate the journey.

The drama therefore won’t focus solely on solving crimes. It will also explore the psychological motivations of its characters and the emotions hidden beneath their relationships.

A Complicated Relationship Between the Three Leads

The dynamic between Teresa, Park Seol, and Yoo Ah Ram could become one of the most intriguing aspects of the series.

Teresa views Park Seol as her teaching assistant, but his constant presence and hidden secrets make him difficult to understand.

Meanwhile, Ah Ram is wary of Park Seol and appears protective of his longtime friend Teresa.

As Teresa becomes increasingly immersed in her investigations, both men remain close to her, potentially creating emotional tension alongside the murder mystery.

However, the exact nature of their relationships remains under wraps.

Ma Teresa Production Team

Ma Teresa will be directed by Jang Young Woo, who previously worked on the hit drama Queen of Tears.

The screenplay comes from Kwon So Ra and Seo Jae Won, the writers behind the upcoming series The East Palace.

The combination of an experienced director and a mystery-focused screenplay has generated interest in the project, particularly with Netflix backing the series.

What to Expect From Ma Teresa

The new Netflix drama is expected to combine several elements, including:

• Unsolved murder cases
• Criminal psychology
• Hidden identities and secrets
• Past trauma
• Emotional conflicts
• Complicated friendships
• Potential romance
• Psychological tension

Nana’s portrayal of a cold and emotionally complex criminal psychologist will be at the center of the story, while Kim Dan and Jung Gun Joo’s characters bring contrasting personalities and relationships into Teresa’s world.

Ma Teresa Will Stream Exclusively on Netflix

Netflix has confirmed Ma Teresa as one of its upcoming Korean series.

The drama will be released exclusively on Netflix, although an official premiere date has not yet been announced.

With Nana leading the cast alongside rising actor Kim Dan and Jung Gun Joo, Ma Teresa is already drawing attention for its darker premise and mystery-driven storyline.

As Teresa gets closer to the truth behind the cases—and the trauma that has followed her for years—viewers can expect a story where solving the murders may be only the beginning of uncovering the real secrets.
