Hyosung flaunts her flat abs and lean legs in yellow 'Adidas' sportswear in one photo, searing the camera with her provocative gaze. In a more intimate picture, Hyosung stares bashfully out from underneath white sheets, leaving up to our imagination what lies underneath. 

In the interview after the photo shoot, Hyosung relayed, "During summertime when you expose [your body] a lot, I refrain from consuming any carbs. Instead, when I'm hungry, I eat fruits and vegetables. Thanks [to my diet], a lot my swelling is gone, I slimmed down, and a lot of my skin troubles that used to pop up whenever I was fatigued is gone too."
