Early life and education Park Seong-hye was born in 1970 in Seoul. She has been a pop culture enthusiast since a young age. Her passion for pop music began in the third grade of elementary school, and she spent her time watching various dramas and award ceremonies on AFKN. As a child, she enjoyed seeing new stars emerge and read numerous books on the subject. "I was more interested in popular culture than studying," she said with a laugh. "Loving to read books has been a great help in managing actors. In high school, I was part of the broadcasting club, and in college, I was part of the film club. In middle school, I loved shows and attended many performances. Sometimes, there were dancers behind the singers, and there was one person who stood out as a great dancer. That person gradually became even better and started dancing right next to the singers. I thought, 'Wow, they finally succeeded. I had my eye on them...' There were people I admired like that, and that person was none other than of ."
After retaking the exam in 1990, Park was accepted into Myongji University's Department of English Literature. During her college years, she developed a keen interest in photography and actively participated in a film club. Additionally, she joined a model agency and model center, where she worked part-time while capturing images of models. Furthermore, prior to graduating from college, she held a position at the Sanulrim theater company. Park believes that her diverse experiences have greatly contributed to her pursuit of a career in management.
In 2006, Park took the comprehensive exam for Hongik University. She took time out of her busy schedule to pursue a master's degree in Advertising and Public Relations at Hongik University Graduate School. In 2011, Park began pursuing a doctorate degree after completing a master's program.
Career Early career as manager After graduating, Park began her career at Nonno fashion company as a marketer. The company went bankrupt six months later, leaving her jobless. Subsequently, she opened a bar called "Alcohol Tank" in Hannam-dong, but it struggled financially. She was later recruited by Star Search, a management company under Saehan Media (Samsung Group), through a recommendation from her former team leader at Nonno. In 1994, Park was selected during the second round of open recruitment for Star Search, which represented actors such as Kim Hye-soo, Shin Eun-kyung, Lee Jae-ryong, Yoo Ho-jeong, Choi Min-sik, and Yum Jung-ah. Star Search typically hired graduates from top universities for their management team, but Park was an exception.
Her initial experiences as a manager were challenging. She started as a manager for Yum Jung-ah before becoming Kim Hye-soo's manager. Known for frequently changing managers due to dissatisfaction, Kim's first impression of Park was critical; she described Park's appearance in an interview as, "Wearing a studded leather jumper and a leather skirt, her hair was like Tina Turner's, and her makeup was like a chimera. Since this woman was my manager, I thought the company had lost its mind." At the time, Kim Hye-soo was already an established star, and Park worked as a 'rookie road manager' with a modest salary of 500,000 won. Her responsibilities included answering calls and accompanying Kim on film sets. However, Park did not drive, requiring Kim to drive herself. Initially, Kim was not fond of Park's working style, which created tension in their relationship. In time, they grew closer through shared interests in music, which helped improve their rapport.
An incident involving a mistake with plane tickets led to a delay in a commercial filming team's departure. Kim Hye-soo responded positively to the situation, expressing her desire for rest despite the financial implications. Park learned valuable managerial skills from Kim, who provided opportunities and a supportive environment.
Park also managed Jeon Do-yeon, who initially perceived her as somewhat arrogant but later became close friends with her. Jeon was particular about script deliveries and finances, but their relationship deepened over time. Park observed that Jeon preferred to form deep connections with a few individuals rather than engage in large social gatherings. Park also mentioned that when choosing roles, Jeon tends to be attracted to characters that are relatable and likable on a human level.
After a few years, Star Search closed down. Park continued to work with Kim Hye-soo while also managing three new actors. She later joined IS 201, a company founded by shoemaker Esquire, which eventually went bankrupt. Park then became Jeon Do-yeon's personal manager and later reunited with Kim Hye-soo.
In 1999, while managing Kim Hye-soo and Jeon Do-yeon, Park encountered Ji Jin-hee, a photographer, and persuaded him to pursue an acting career. After a year of encouragement, Ji Jin-hee transitioned to acting and achieved success, particularly with MBC's Jewel in the Palace.

This signaled a change in Park's management strategy, especially in terms of connecting with a younger demographic. "I used to be concerned that appearing on TV could harm the actor's brand image. But audience tastes change quickly, and if you're not in the spotlight, you can quickly fade into obscurity," Park explained.The Dong-A Ilbo
In 2004, Gong Hyo-jin, Kim Sun-a, Kim Soo-ro, Yum Jung-ah, Kim Sung-soo, and Gong Yoo joined the agency.

In 2005, Sidus HQ actively sought to expand their talent roster by signing several new artists. On April 8, they welcomed Song Hye-kyo, signing her to an exclusive 3-year contract worth 300 million won. Later, on May 20, they also signed exclusive three-year contracts with talent Han Go-eun and Jo Yoon-hee. Sung Yu-ri joined in june, and Kim Jung-hwa became a part of the agency in July after her contract with the former agency Dream Factory ended. Sidus HQ emerged as the top choice for many celebrities entering the free agent market in 2005. By August, about 70 stars, including top names like Jun Ji-hyun, Song Hye-kyo, Sung Yu-ri, Kim Hye-soo, Jeon Do-yeon, Jung Woo-sung, Jang Hyuk, and Zo In-sung, belonged to Sidus HQ. In December, Kim Seo-hyung also signed a three-year contract with the agency. In that same month, Kim Sung-hoon, who debuted in the 2003 film Madeleine, signed with SidusHQ and adopted the stage name Ha Jung-woo on their recommendation. Sidus HQ emerged as the top entertainment company in Korea, with their actors Kim Sun-a, Jeon Do-yeon, and Hwang Jung-min sweeping the 2005 year-end awards.
Voices of concern were growing due to the rapid and aggressive expansion of the management industry in 2005. In 2005, concerns were raised about the rapid and aggressive expansion of the management industry. Chungmuro producers were particularly dissatisfied with Sidus HQ, which had significant negotiating power with top stars. This led to criticism from producers who felt that Sidus HQ was leveraging actors to boost the management company's power excessively. However, some viewed Sidus HQ as a model for latecomer management companies to emulate.
In 2005, Park advanced to become the head of the management business division. Park's team included actors recognized for their acting skills, such as Hwang Jung-min, Im Soo-jung, Gong Hyo-jin, Yoon Jin-seo, Kim Sung-soo, Gong Yoo, Yum Jung-ah, and Ha Jung-woo. That same year, Park participated in a public hearing on the Personal Information Protection Act, highlighting a case of false celebrity information leakage that underscored societal insensitivity toward personal information and human rights.
Park advanced to become the head of the management business division and later in 2006 the content business division. She is recognized for her attention to detail, swift grasp of market trends, and adept assessment of each actor's position and career path. Her duties included script reading, with her desk frequently overflowing with scripts. She commented on the challenge of managing the volume, stating, "There are so many scripts that it's hard to read. These are the ones I'll read today. Eighty percent of the management work is rejection." Her habit of extensive reading has honed her ability to evaluate scripts and scenarios effectively.
During Park's tenure as director of the content division, IHQ, the parent company, achieved a market capitalization exceeding 300 billion won. By 2006, Sidus HQ emerged as the largest management company in Korea. This growth was attributed to many prominent figures in Korean entertainment being affiliated with the company, managing over 90 stars and newcomers, and engaging in various business ventures. Considering the size of the popular culture market, Sidus HQ reached a level comparable to that of Creative Artists Agency in the United States and Yoshimoto Kogyo in Japan.
