Group 2AM members took a picture together.

On August 7, Jo Kwon posted a picture on his Instagram with, "2AM all together. Tomorrow is JYP Nation. Fighting."

In the picture, the 2AM members are sitting together during a concert rehearsal. Despite being playful normally, the members looked serious as they waited for their turn.

In response, people said, "2AM fighting", "Long time no see", and "2AM, I'm always cheering you on".

2AM will participate in the '2014 JYP NATION' concert starting August 9 in Seoul.
