Rookie A-JAX member Yunyoung becomes known as the 'idol with conscience'.

A photo of Yunyoung after a filming of a TV show has become popular among internet users.

On June 28, these sets of photos that were taken after the June 23 broadcast of MBC 'Show! Music Core' was posted on the A-JAX official fan cafe. The photos are of Yunyoung cleaning up the room by himself after the broadcast.

Yunyoung is not only picking up the trash on the floor but also separating the plastic bottles for recycling.

Along with the photo, the caption read, "This photo was not set-up in any way. Yunyoung, who pays attention to details, usually cleans up the room on his own."

Internet users commented, "He is an idol with a conscience" and "His face and his heart are both warm."
