Yoo is best known for her work as scriptwriter of KBS television series Secret Love (2013), JTBC mini-series Rain or Shine (2017) and Reflection of You (2021), as well as her critically acclaim film Snowy Road (2017).
[2] In 2008, Yoo collaborated with Park Jung-bum, a fellow alumnus of Dongguk University's Graduate School, on a short independent film script titled 125JEON Seung-chul.
It depicts the story of Seung-cheol, a North Korean defector portrayed by Park Jung-bum, who has recently left Hanawon.
The detective in charge of Seung-cheol introduces him to a factory, but he faces rejection due to his status as a North Korean defector.
[3][4] In 2011, Yoo won the Grand Prize in the KBS 24th TV One-act Drama Contest for her script, "A Spoonbill Flies Away."
[5][6] The script written by Yoo was selected to get production support work in from the Korea Creative Content Agency for the one-act play category.
The drama follows Do-hyeon (played by Lim Ji-gyu), an unknown action actor who unexpectedly becomes a taekwondo instructor at his alma mater.
The four winning works from the previous year's One-Act Play Script Contest were broadcast every Sunday at 11:15 pm for four consecutive weeks, starting from October 28, 2012.
Lee Moon-sik played the lead role of Sang-kwon, a construction worker who has lost his family and struggles with memory loss when drunk.
The story follows Yeon-woo (Han Ye-ri), an indie band singer-songwriter who took over the family business after her father passed away, runs a home appliance repair shop, and works part-time at a cafe while going to work to replace her mother, Park Soon-im (Kim Hye-ok), a building sanitation worker who was hospitalized in a traffic accident.
[13] Secret Love starred Hwang Jung-eum, Ji Sung, Bae Soo-bin, and Lee Da-hee in the lead roles.
[14] Secret Love garnered positive reviews consistently for its well-structured portrayal of a passionate melodrama involving four characters intertwined with revenge and desire.
[15] The success of Secret Love was attributed to the combined talents of promising new writers and the planning skills of the production team.
Hwang Eui-kyung, the Chief Producer of the KBS drama department, acknowledged that broadcasting companies traditionally hesitated to hire new writers, especially for mini-series, due to the financial implications and increased risk.
Directed by Park Jung-bum, the film is a mystery thriller that portrays a dramatized version of a real-life murder case that took place at a raw fish restaurant in Gangwon-do.
