Heo Sung-tae, working with Jung Hae-in and Ha Young… Netflix 'This F***ing...'

Heo Sung-tae to Bring 'Intense Presence' to Jung Hae-in and Ha Young's Rom-Com

Actor Heo Sung-tae is joining the Netflix original series 'This F***ing Love.' His agency, Billions, officially announced on the 13th that Heo has been cast as 'Baek Sang-gil,' a gang boss who will serve as a key figure in controlling the tension of the drama. The project is a romantic comedy that is garnering attention with Jung Hae-in and Ha Young in the lead roles.

The character Baek Sang-gil, played by Heo Sung-tae, is a multi-dimensional figure that goes beyond a simple villain. While he maintains a dignified image as a businessman in society to gain public trust, he is actually a cold-blooded boss running an organization. In particular, he possesses a cruelty that reveals his hidden nature when betrayal occurs. He will stand in sharp opposition to the protagonist Jang Tae-ha (played by Jung Hae-in), playing a role that injects heavy crime narrative tension into the romantic comedy genre, which could otherwise feel light.

Heo Sung-tae has built a unique character profile by moving between films and dramas. Not only did he make a name for himself worldwide through the Netflix series 'Squid Game,' but he also delivered powerful performances in major works such as 'The Roundup' and 'The Fortress.' Having proven his acting skills by winning the Best Actor in a Film award at the Korea Culture & Entertainment Awards and the Best Supporting Actor award at the KBS Drama Awards, he seeks another transformation through this work.

The Strange Cohabitation of an Amnesiac Prosecutor and a Boxing Coach

'This F***ing Love' has a unique premise. It depicts the commotion that ensues when Go Eun-sae (played by Ha Young), a prosecutor who has lost her memory, and Jang Tae-ha (played by Jung Hae-in), a boxing coach who claims to be her boyfriend, end up living in the same house. The relationship between the female lead, whose memory has vanished, and the male lead, who seeks to monopolize her past, serves as the central driving force of the drama.

The production team is also impressive. Director Kim Jang-han, who showed sensible directing skills through 'Do You Like Brahms?' and 'My Demon,' has taken the helm. Additionally, writer Mo Ji-hye, who wrote 'You Raise Me Up,' has teamed up with Director Kim Jang-han once again. As the two production members reunite after four years, expectations for the quality of the work are high.

Baek Sang-gil, played by Heo Sung-tae, is expected to act as a variable that creates cracks in their peaceful or chaotic cohabitation life. Within the cheerful flow of the romantic comedy, the pressure created by the character Baek Sang-gil is expected to regulate the overall pacing of the drama.

From a Large Corporation Employee to an Actor of Substance: Heo Sung-tae's Trajectory

Heo Sung-tae's journey is dramatic in itself. He did not immediately pursue acting right after graduating from university. After gaining social experience working in overseas sales at a large corporation, he challenged himself to act at a somewhat late age. He took his first step into his acting career through the 2011 SBS show 'Miracle Audition.'

The solid inner strength forged on set allowed him to grow quickly into a leading-class actor. In 2025, he expanded his acting spectrum by securing his first main lead role since his debut in the film 'The Informant.' Recently, he showed his presence by exuding heavy charisma in the drama 'Fifty Percent,' and he continues his relentless schedule with upcoming appearances in 'Reborn Rich 2' and 'Crash 2: Road of Fury' in the second half of this year.

Confirmed for Netflix Release on August 7

The new synergy created by Jung Hae-in, Ha Young, and Heo Sung-tae will be released to viewers worldwide through Netflix on August 7. The key point of interest for this work is how the narrative of a gang boss will be integrated into the romantic comedy genre.

Through this work, Heo Sung-tae faces the task of how he will embody Baek Sang-gil, who possesses two faces—a businessman and a boss—going beyond the intense villain image he has previously shown. As it targets the global market as a Netflix original series, the industry's attention is focused on how his acting transformation will affect the success of the work.
