JYJ's Yoochun picked up a microphone for 'I Miss You'.

The MBC drama revealed a still cut with a microphone in hand. The 'I Miss You' staff said, "The scene with Yoochun holding a microphone is the linking the story from the child actors to the adult actors. The clue is in the episodes with the younger characters. It's the first scene with the adult Han Jung Woo, so we hope viewers look forward to what kind of story will be told".

Yoochun made his first appearance on 'I Miss You' for a short time at the end of the 2nd episode, saying, "I'm just going to wait today. I'm going to go crazy like this".
