A close acquaintance of singer Hwanhee guest starred on the August 13th episode of�KBS2TV's 'Secret' and revealed some interesting pointers given to him by the singer. Hwanhee's friend showed the audience everything Hwanhee taught him about girls and dating-- pretty much that nice guys finish last and that the "bad guys" always win. He gave specific demonstrations of how to talk to girls on the phone and how to coax girls after a fight. He also mentioned that Hwanhee also has a cute hidden side of him that's so different from the Hwanhee who taught him to be the "bad guy". Although Hwanhee was a bit taken aback by all this, his friend and Shin Bong Sun acted out how Hwanhee deals with girlfriends after an argument. Hwanhee is currently promoting his new song, "Love Pain". Source & Image: MyDaily via Nate
