On the June 17 edition of On Style's 'Jessica & Krystal,' the Jung sisters, Jessica and Krystal, enjoyed a very fun time in New York City as they had a photo shoot in the trendy Soho area.  In the van, the two provide a lot of laughs as Krystal teases Jessica with Girls' Generation's "Mr.Mr" and they both have fun with "I Got A Boy" and Psy's "Gentleman," even mimicking his dance moves.

However, once they arrived in Soho for the shoot, they become professionals, asking the director what to do and posing coolly.  They also enjoyed some leisure time at what appears to be Bryant Park!  

In addition, in the interview portion, the sisters again expressed their affections toward each other.  Jessica said, "We try to make it fun for each other.  It would have been difficult if we did not have each other." 

Krystal added, "If we were not in the same career field, I don't think we'd be this close.  We understand each other better than anybody because we do the same thing."  Jessica said, "I really like that."
