2AM's leader Jo Kwon recently shared some photos featuring his fellow JYP Nation members, showing fans their close, family-like bonds. On July 31st, Jo Kwon tweeted, "JYPNation Concert practice", and attached four selca pictures with Wonder Girls' Sunye, miss A's Min, and rapper San-E. It's been known for a while that Sunye and Min are two of his closest friends in the company, as they trained with him the longest. Even now, the three look so tight with one another that one could easily mistake them as siblings. Meanwhile, the 'JYP Nation Concert' will be held in August, which will feature performances by 2PM, 2AM, Wonder Girls, miss A, San-E, and Joo. Source: TV Daily via Nate
