On July 21st, SNSD's Sooyoung made a surprise appearance along with producer Kim Hyung Suk at a press conference for the upcoming movie 'Pain', starring Jung Ryeo Won and Kwon Sang Woo. Actress Jung Ryeo Won was taken completely by surprise at Sooyoung's appearance, and commented, "We became close friends while studying the Bible together." Sooyoung explained , "We've been good friends for about two years now. She has a really cool personality, and usually loves to party and play, but I was really impressed when I saw how much effort she puts into her work." She added with a laugh, "Of course, we're not doing inappropriate things when hanging out, so please don't misunderstand." Sooyoung continued, "I'm friends with writer Kang Pool, and I heard that his comic 'Pain' was being turned into a movie. I had read the comics, so I was really curious as to how the movie would turn out. But then I heard that my close friend Jung Ryeo Won-unni had been cast in the movie, and became even more curious as to what the movie would be like." Jung Ryeo Won added, "Sooyoung is 22 years old, so there is a 9 year difference between us, but I think our souls have the same age. We get along well, so we became close very easily. We talk about many things during Bible study, and usually meet often to talk." Writer Kang Pool's comic-turned-movie 'Pain' describes the love story between a man who cannot feel pain (Kwon Sang Woo) and a woman who has a disease that causes her to feel immense pain from even the smallest wound (Jung Ryeo Won). It will be released in theaters this upcoming September. Source + Photo: TV Daily via Nate, Seoul NTN, OSEN, Dailian via Daum
