After School's Nana looked back on her supermodel days on the last episode of Sweet Night, which featured After School and HaHa as the guests. During the episode, a footage of Nana before her debut with After School was played. Some of you guys may know this already but Nana used to be supermodel, which isn't surprising at all since she is gorgeous and has a body to die for. In the footage, Nana said to the judges at a supermodel competition, "I will work to win with my own colors." This made the guests all crack up. Nana said about the competition, "I had to be content with being qualified for the round. I didn't win." Then, Nana showed off her model walk in the studio and wowed the guys.
