Goo Hye-sun Dons a Scientist's Coat, Joking About KAIST Students' 'Loving Anger'

Actress Goo Hye-sun playfully expressed her 'loving anger' towards KAIST engineering students.

On the 22nd, Goo Hye-sun posted a message and photos on her social media account, saying, "I went dressed up in a sparkly outfit for promotion, but the KAIST geeks made me wear a scientist's coat!!!! (I really love you)"

The published photos show Goo Hye-sun wearing a scientist's coat with the KAIST logo. This was in contrast to her full makeup and efforts to promote her patented 'G-Roll' hair curler. Notably, Goo Hye-sun, who was taking photos with excitement, flaunted her slim figure, seemingly having succeeded in her diet. Due to the short skirt, her hip line was also somewhat exposed.

Goo Hye-sun's patented 'G-Roll' is based on her idea and design, reinterpreting traditional round hair rollers. It applies a high-functionality polymer composite material finished with silicone laminating, using a wave mold structure instead of a metal flat plate. This allows the hair roller to be easily unfolded and folded flat, and its size can be freely adjusted as needed, maximizing portability. Furthermore, through its structural design, it achieves a 'self-restoring' function that returns to its original shape with just a light snap, without any external heat or electrical stimulation. The consumer price is 12,800 won (for 2 pieces). Currently, a single-piece limited edition is being sold for 6,400 won on the official website.

After its launch, Goo Hye-sun appeared on live shopping to promote the product. Although she transformed into a lovely, feminine style for the promotion after a long time, her femininity was overshadowed by wearing the scientist's coat, bringing laughter.

Meanwhile, Goo Hye-sun legally divorced Ahn Jae-hyun in July 2020 after reaching a settlement in divorce mediation. Recently, she also indirectly addressed Ahn Jae-hyun, stating that her daily life was being consumed by their divorce.

Netizens commented, "Goo Hye-sun is so cute," "The scientist coat suits her well," and "I really want to try the G-Roll!", responding positively to her witty communication style.
