Actress/DJ Yoo In Na shed a few tears after she was given a warm surprise from fans of her radio show, 'KBS Cool FM Raise the Volume'.

To celebrate her 100th day as the show's current DJ, the staff put together a special surprise for Yoo In Na. They chose ten fans and pre-recorded a message of congratulations which aired live during the show.

As Yoo In Na introduced the next song, the surprise message began to air, much to Yoo In Na's surprise. She shed tears as she heard messages like, "Yoo In Na's charm lies in her honesty. We hope DJ Yoo will spread her happy virus to even more listeners in the future."

Since the radio show takes place in an open studio where fans could peer into the recording, they waved tissues and cheered her on from outside.

After the show, Yoo In Na gave out gifts of chocolate along with her thanks to fans waiting outside the studio. She stated, "I was really surprised at the special message! Thank you so much. Rather than Valentine's Day, today is Volume day!"

With the special surprise, the show attracted three times the amount of listeners than usual.
