In the latest preview for Cinderella's Sister, 2PM's Ok Taecyeon's character Jungwoo is heard talking with a saturi (country dialect/accent). In America you have the southern accent (country) or Brooklyn accent and Korea has different accent / dialects as well, which is called saturi. Nate News recently revealed that Taecyeon was taught private lessons in saturi from fellow 2PM members Junsu and Wooyoung. Both Junsu and Wooyoung hail from Kyungsangdo, where saturi is prevalent. It's been also revealed that as the story progresses and Taecyeon grows into a man, he'll try to fix the saturi and only speak it to the women he loves, Eun Jo (Moon Geun Young). Seems like things are going to get interesting on Cinderella's sister, the next episode airs on April 14th. Thanks to jinjin for the tip.
