The male group 2AM revealed their practice.

On October 30, Jo Kwon posted on his Instagram, "Practicing together for the first time in a while" along with a picture.

In the picture, 2AM members are standing in a line in the practice room. They are all in casual outfits but they still showed off perfect body proportions.

Internet users who saw this commented, "Wow absolutely the best. I missed the four of you together," "Go 2AM," and "I can't wait."

2AM will be releasing their new album on October 30 and hold their comeback stage on October 31 through KBS 2TV "Music Bank".
