Lady Jane explained to Ilgan Sports, saying, "I did not undergo surgery at all. To be honest, performing on 'Mask King' was incredibly overwhelming. I lost 6kg (~13lbs) while practicing. I think that's why my face looks slimmer. I did not get any touching done." She also chuckled and said, "It's good to hear that I look prettier."
