Soyu showed off her slamming figure in sexy one-piece dresses for the photoshoot, and she revealed that she works hard for her body. "I eat a lot. To make up for it, I work hard to keep fit and try to think positively. When I want to 'up' my mood these days, I exercise. After I sweat it, I feel refreshed."
