2AM Seulong posted a pic of Jinwoon's self-cam photos.

On June 24, Seulong posted on his twitter, "Jung Jinwoon...I think he is bipolar. He smiles then goes crazy. I'm scared to be with him in the house," along with a photo.

In the photo, Jinwoon smiles into the camera in one picture and looks as if he is screaming with rage in another.

Internet users commented, "What the...that's scary" and "I guess this is what 2AM does in their spare time."
