To celebrate her 1-year anniversary on KBS Cool FM's 'Yoo In Na's Volume Up', actress Yoo In Na wrote a handwritten letter for her fans.

Yoo In Na recently updated her me2day with photos of her letter along with the post, "I wrote a letter. Hehe. My handwriting is a mess, so I don't know whether or not you'll be able to read it~^^ I don't know of an easier way to upload this...This is the best I could do;; Good night everyone. I'm also going to go to sleep for a bit. Students who are taking the college entrance exam, dress warmly and don't forget to eat your breakfast!! The world is yours! There's no need to be afraid!"

Her letter begins: "November 7. It has been exactly a year since I became a DJ on 'Volume Up'. A lot of people congratulated me so I arrived home in a great mood. It's already past 4 in the morning after reading all of the letters [from fans] one by one."

She then goes on by writing, "There were some who even wrote me a letter just before their college entrance exam. The exam is beginning in just a few hours now. Are you guys all sleeping well? I'll be cheering for you guys throughout first and second class."

"I'm always reading your letters. Thank you. There were so many things that I wanted to say, but I can't think of them now. I'll be staying here for a long time. Bye my loves."

Yoo In Na became a DJ for 'Volume Up' on November 7th of last year by taking over Choi Kang Hee's position, who had to step down due to her busy schedule.
