We have reported about Choi Siwon's chocolate abs pictures which have made headlines over the past week and how he had been working his socks off, losing 8kg. All his effort made was for his drama, Oh! My Lady where he plays the leading role opposite Chae Rim. The story is kind of similar to a certain drama from the past where Choi Siwon plays a top star, Sung Min Woo while Chae Rim plays a housewife who later becomes his manager. Hilarious situations ensues thereafter and you can now check out the subbed trailer which features a lot of Choi Siwon and also his abs. The drama will premiere on March 22nd through SBS http://www.youtube.com/watch?v=DHNGsUbcfrk
