He wrote on his Twitter on May 13, "It's been 100 days since 'Jonghyun's Blue Night,'" and uploaded a picture. In the picture, he is in the radio booth, wearing a cap that covers his eyes but not the cute smile as he holds a celebratory cake!
Jonghyun replaced Jung Yeop as the DJ back on February 3. He had previously stated, "I liked listening to the radio for a long time and wanted to be a radio DJ since I debuted. I finally get to be one!"
Congratulations to Jonghyun on reaching the 100th day and there will surely be many more great days to come.
