Their chemistry is what fans are most excited about, and judging by the teasers and stills, it looks incredibly promising.
Notably, Lee Sung Kyung is making her first full-fledged return as a leading actress in two years since Dr. Romantic 3. Although she made cameo appearances in Dr. Slump and The Player 2: Master of Swindler, this marks her true comeback in a main role.
On the other hand, Lee Dong Wook recently starred in The Divorce Insurance and is now preparing for Season 2 of A Shop for Killers on Disney+.
Since The Nice Guy airs this week, here’s everything you need to know from release date to cast, plot, and more.
The Nice Guy Release Date
The noir melodrama, The Nice Guy, starring Lee Sung Kyung and Lee Dong Wook, is set to premiere on July 18, 2025, at 8:50 p.m. KST and conclude on August 29. The 14-episode series will air two back‑to‑back episodes every Friday and stream internationally via Viki and Disney+ in select regions.
Plot
Described as a “sentimental noir,” the drama follows Park Seok Cheol (Lee Dong Wook), the eldest grandson in a third-generation gangster family. He once dreamed of becoming a novelist like Ernest Hemingway, but family ties forced him to swap his pen for a life of violence. His weary, empty life is turned upside down when he coincidentally crosses paths again with his first love, Kang Mi Young (Lee Sung Kyung).
Mi-young is an aspiring singer held back by stage fright, endless part-time jobs, and heavy family burdens. Seeing Seok Cheol again gives her new hope, both for her life and her music.

The Nice Guy Trailer
The recently released character posters highlight the cast’s emotional struggles. Seok Cheol appears bruised and weary in a subway, while Mi Young gazes longingly as she sings.
The tagline, “It’s okay if my life falls apart a little,” hints at the series’ melancholic yet hopeful tone.

Production Team
The Nice Guy brings together directors Song Hae Sung and Park Hong Soo. Song Hae Sung is known for films such as Failan and Maundy Thursday, while Park Hong Soo previously directed Lost.
During a press interview, director Song Hae Sung said the show’s atmosphere is meant to feel like a throwback to the 1980s and ’90s, mixing first love with gangster life. He said, “We aimed for something subtle, like Pyongyang cold noodles — simple at first but lingering in your mind.”
The script is crafted by Kim Woon Kyung, who wrote Yoona’s Street and The Moon of Seoul in partnership with Kim Hyo Seok, the screenwriter of Yadang: The Snitch.
Produced by Hive Media Corp, SLL, and HIGROUND, this series also marks Hive Media Corp’s first step into TV drama production, following hit films like Harbin, 12.12: The Day, The Man Standing Next, Handsome Guys, and Inside Men.
