Actress Koo Hye-sun played an active role in 'Radio Star'.
In the MBC entertainment program "Radio Star," which aired on the 21st, Koo Hye-sun appeared as a guest.
Koo Hye-sun, who visited "Radio Star" last year, played an active role by giving off pleasant talk. Koo Hye-sun, who has had an ever-changing year since then, drew attention with her "Dr. Koo Moment." He announced his early graduation from his master's degree at KAIST.
In addition, Gu Hye-sun honestly delivered an episode worthy of the "As You Say It" special. He said he usually confides in his goals in words first, and then revealed his own method of constantly trying to make his dream come true. His career, which he has built up in various fields, including directing, composition, and painting, proved this, providing a warm sound.
Koo Hye-sun's unexpected charm also exploded. He recently became a master of claw machines after studying how to increase the winning rate of claw machines. Koo Hye-sun also drew attention by holding a bunch of dolls she picked herself to present to other cast members.

In addition, Koo Hye-sun honestly mentioned wearing a hat, which was controversial when she appeared last year. At the time, he was controversial for wearing a fur hat without washing his hair due to a boiler failure.
In response, Koo Hye-sun said, "At that time, I was sorry that the producer apologized for me. People around me sent me a consolation text or kakaotalk. Our people have long been equipped with hats and shoes from the head. He apologized, saying, "I sent a lot of such memes."
Kim Gu-ra said, "I paid a lot of attention to my hair today," and Koo Hye-sun said, "I also wore flowers today. At that time, there was a main character in 'Rath'. It was Choo Shin-soo. That's when he retired and appeared. It's a very happy day, but I was so sorry for my hat," he said.
In addition, Koo Hye-sun said, "At that time, I showed my hair roll on the show because of my graduation from school. The KAIST professor contacted me after seeing the head disturbance. This has become a blessing in disguise. I'm going to release a hair roll with KAIST professor. With that, he became the CEO of a venture company. I also received the patent award," he said.
