2AM's Jo Kwon gave fans a glimpse of the 2013 2AM Calendar.

The calendar was released on December 13th, and Jo Kwon took photos of the calendar so fans who haven't bought the calendar could see what it was like. He snapped photos of their group shots and his solo shots. In the photos, he's smiling warmly at the camera, showcasing a soft charm, that was different from how he was on variety shows.
