Actress Ku Hye-sun has embarked on a new challenge as an inventor and representative of a venture corporation. This is exciting news following her patent.
Previously, she graduated from Sungkyunkwan University with a degree in film studies after 13 years, inventing a hair roller product to meet the graduation requirement known as the 'three-product system' and applied for a patent, which was officially registered in December 2021.
Afterward, Ku Hye-sun enrolled in the graduate program in science journalism at KAIST, pursuing her master's degree, and established a venture corporation based on the hair roller product. Everyone was surprised by the news of her unexpected role as a corporate leader.
Officially, on May 28, 2025, she received the 'Preliminary Venture Corporation Confirmation' and took her first step as the representative of a venture corporation, also revealing the confirmation. This confirmation is valid until May 27, 2028, and Ku Hye-sun announced this new beginning through social media.
The hair roller product can be expanded and rolled up, highlighting its design for portability and practicality. Ku Hye-sun expressed her hope for this product to be utilized in services such as airplane service, revealing that she participated in the development with a professor from KAIST, drawing attention.
In this way, Ku Hye-sun is active in many areas beyond acting, directing, and writing, as an inventor and representative of a venture corporation. Many people are showing interest and support for her new challenges, saying, "That's really amazing," "Wow, I shouldn't give up either," and "What a fantastic sister."
Ku Hye-sun's divorce from actor Ahn Jae-hyun was legally finalized in July 2020 following an agreement on divorce mediation.
