Media outlet 'The Fact' released pictures that were taken on September 21 of f(x)'s Luna with a man in Seoul.  The two appear to be close as she leans back into his arm while they both laugh and more. These pictures were uploaded onto 'The Fact's Facebook on September 22 along with the question, "Luna on a 'Walking Date' on a Sunday with a nice guy...lover or friend who's the guy?"  

Reportedly, the two engaged in friendly skinship as they walked along and took the subway, patting each other's hips and putting each other into a headlock.

SM Entertainment answered the question of 'lover or friend who's the guy' for the media outlet.  A rep told 'The Fact,' "Luna was on her way to church that morning.  The man next to her is a close friend she knew since she was young with whom she goes to church.  They were on their way to church together on that day, as well.  He is not her boyfriend."
