What’s the Story About?
“Materesa” centers on Ma Teresa (Nana), a cold-blooded criminal psychologist and professor who consults on unsolved murder cases that have made national headlines. She’s joined by Park Seol (Kim Dan), her teaching assistant whose innocent exterior hides a deeper secret, and Yoo A Ram (Jung Gun Joo), her longtime friend and a prosecutor who keeps a close, wary eye on Park Seol’s growing proximity to Teresa. As Teresa personally interrogates suspects and pieces together long-buried clues, she finds herself increasingly swept up in emotions she didn’t expect.

Meet the Cast
Nana takes on the title role of Ma Teresa, a woman carrying her own past trauma while diving deep into cases others have given up on. The role promises both her character’s hardened intensity and a more vulnerable, complex inner side.
Kim Dan plays Park Seol, whose warm smile conceals suppressed emotions and an unpredictable streak — a character clearly designed to keep viewers guessing about his true motives.
Jung Gun Joo rounds out the trio as Yoo A Ram, portraying the prosecutor’s delicate emotional balancing act between loyalty to Teresa and suspicion toward Park Seol.
The Team Behind the Camera
“Materesa” is directed by Jang Young Woo, best known for helming the massively popular “Queen of Tears” and the fantasy drama “Bulgasal: Immortal Souls” — a strong signal of the emotional depth and polish fans can expect. The script comes from writers Kwon So Ra and Seo Jae Won, previously behind “The East Palace.”
Where to Watch While You Wait
