Sunny wrapped up her last day on fellow SNSD member, Tae Yeon radio show, Chinahn Chingoo. She participated in a segment called "Girls Talk" corner alongside Tae Yeon and Park Ki Young. Recently, last week was her last time on the show and singer, IU, has now replaced her. Reasons for this change are unknown, most likely because of Sunny's schedule for Invincible Youth and whatnot. Good luck to IU and Sunny!
