Park is better known in recent years for his villainous roles in the dramas The Glory (2022–2023) and Queen of Tears (2024), as well as playing the transgender ex-soldier Cho Hyun-ju in Squid Game season 2 (2024).
Park Sung-hoon, the youngest son with two older sisters, was born on February 18, 1985, in Gwacheon, Gyeonggi Province. He faced financial hardships during his upbringing because his father lost his job at the bank as a result of the IMF crisis. Despite attending French class of Gwacheon Foreign Language High School, he did not find much interest in studying. It was only during his third year of high school that he began contemplating his future career. This led him to enroll in Dong-ah Institute of Media and Arts, majoring in acting and film, as he had always been fond of movies.
At the age of 20, he took on his first lead role in a school class workshop, portraying Deokbae in the play titled Taxi Driver, written by director Jang Jin. He put on one performance every semester and the experience left a lasting impression on him. As he continued to participate in theater, he became more passionate about it. It was only later when he heard seniors describe the feeling of performing and receiving applause as akin to taking drugs that he realized the allure of the stage. From then on, his interest in theater only grew stronger.
After graduating, Park worked in the theater company Route 21. He was also doing odd jobs to make a living. He spent about 8–9 months in the theater company, and while he enjoyed the stage work, he found it frustrating. He had to work part-time until late at night, sleep in the theater, and couldn't secure a role due to teachers and senior actors receiving priority. He also only earned 50,000 won in total for those 9 months.
Following his departure from the theater company, Park secured minor roles in the films A Frozen Flower (2008) and Jeon Woo-chi: The Taoist Wizard (2009). Even after his film debut in 2008, Park endured a three-and-a-half-year period without any acting opportunities. After joining an agency, Park's opportunities remained limited. In the span of a year and a half, he only auditioned three times, which left him feeling disheartened about his career prospects. In 2009, he applied for the KBS voice actor recruitment test but failing in the final interview. To survive, he took on part-time employment at a concert hall, assuming the roles of both an announcer and a merchandise vendor; first in the musical concert "Pump Boyz," "Hedwig Show," and Yoon Do-hyun's Band Concert. Park's job at the concert hall allowed him to observe senior artists' performances. He frequently received business cards by chance, which led to many meetings. Fortunately, Park crossed paths with the Shownote team leader, who connected him with people in the theater industry.
In 2011, Park had the opportunity to act on stage even though he had little acting experience. During his performance in his first theater play, Inside the Minke Whale, the joy of acting that he had forgotten about was rekindled. The following year, he also took on minor roles in two television dramas, which as soldier in MBC historical drama Moon Embracing the Sun and as high school student KBS2 drama Big. Shortly after, Park joined the fifth season of the popular play Rooftop Room Cat, for which over 1,000 actors applied.

Simultaneously, he met the audience in the role of Seo Min-yeong, a model student with a shrewd paranoia, in the play Model Students. Juggling two different projects simultaneously and switching between such contrasting characters was undoubtedly challenging. Nevertheless, Park found enjoyment in the process.
Following a short break, his next project was a guest appearance in John Cariani's omnibus play Almost, Maine. This performance was a special stage commemorating the 10th anniversary of the theater company Ganda. Producer Ahn Hyeok-won invited him and Park's decision to participate as a guest was influenced by his agency mates, Jin Seon-kyu and Lee Hee-joon, who were members of Ganda. In the fifth episode titled "They Fell", Park appeared as Chad opposite Yoon Na-moo as Randy, with whom he had previously worked in the play Model Students.
In 2014, Park appeared as a communications team leader in SBS drama Three Days and gained great experience by working with talented seniors.

In the end of that same year, Park and Jo Kang-hyeon both portrayed the character Park Jae-hyun in the play Melodrama directed by Jang Yu-jeon.

Park expressed that after working on heavy projects consecutively, he wanted to do a comedy, and University of Laughs provided him with that opportunity.

In 2024, Park starred as the transgender female character Cho Hyun-ju in the second season of Squid Game. His casting choice was controversial due to some wanting a trans person to authentically portray their experiences. Criticism fell on both the casting of a cisgender person for the role instead of a transgender person, as well as for casting a man in particular as opposed to a woman. Some argued in response to this criticism that South Korea is conservative with regards to LGBTQ rights, and that trying to find a transgender actress willing to put herself in the spotlight was not reasonable. People also opined that having a trans character in a South Korean series at all is an important step in representation. Though Hwang wanted to cast a transgender actor for the role, it was difficult to find such an actor in Korea due to the above issues, and believed that Park's prior roles in The Glory and Queen of Tears made him capable of portraying the role. Of all the cast members of the second season, Park's portrayal of Hyun-ju won significant praise from many critics.
