In the teaser, Jo Kwon puts down a clock with the hands at 2 o' clock. The second hand passes the time, but quickly rewinds back, which may be an allusion to his group 2AM.
The end of the teaser also reads 'Dawn', which may be the title to his comeback song.
Check out the clip above. Jo Kwon's full comeback will be on January 10 at 6PM KST.
