Actress Ku Hye-sun shared an update on her participation in the Himalayan Kanchenjunga expedition. On the 23rd, Ku Hye-sun posted on her social media, "Himalaya. On the way to Kanchenjunga. Wishing for success. Victory!" along with photos taken locally. In the photos, Ku Hye-sun posed holding a dog, dressed in a fur hat, scarf, and hiking clothes, showing a relaxed smile.

The "Himalayan Kanchenjunga Expedition Team," which Ku Hye-sun joined, is a project wishing for the South Korean national soccer team to reach the quarterfinals in the 2026 North and Central America World Cup. Several celebrities, including Lee Jong-won, Kwon Oh-joong, Hwang Seung-eon, and Hwangbo, are participating together. The expedition team plans to travel various routes such as Sacheon, Jongri, and Ramuni over about ten days, heading toward the Kanchenjunga base camp, the world's third highest peak.

Ku Hye-sun recently launched her patented hair roller "Kurol" and started a business as its CEO. The product is sold at 13,000 won per piece and 25,000 won per set, which sparked controversy over the high price. Regarding this, Ku Hye-sun explained, "There were some comments that it was expensive. The processing itself is completely different from existing rollers. There is no plastic, and it goes through a fourth processing stage. The production cost is quite high. Compared to other rollers, it is expensive, but it is not expensive on its own." Recently, she also expressed her gratitude, saying, "Kurol has surpassed 10,000 units sold. Thank you."

In terms of academics, she completed a master's degree in engineering at the KAIST Graduate School of Science Journalism in less than two years. Ku Hye-sun married actor Ahn Jae-hyun in 2016 but divorced after four years in 2020. Since then, she has been actively engaged in various fields, including academics, entertainment activities, and business.
