As previously mentioned, "Mary Skipped the Curfew" has three main protagonists.  First and foremost, there is Moon Geun Young, who will play the role of Mary, a cheerful girl who will experience 100 days of virtual marriage with two men!  Mary's first suitor is an independent band's lead vocalist, Kang Moo Kyul, which perfectly suits actor Jang Geun Suk, who recently played as a lead idol in "You're Beautiful".  The other contender for Mary's hand in marriage is entertainment agency CEO, Jung In, who is a Korean by blood, Japanese in mind, and American in style. Jung In will be played by Kim Jae Wook, a popular model who played the role of Hong Tae Sung in "Bad Guy". Kim Jae Wook stated, "Although Jung In's corporation is perfect, he suffers from emotional instability. This humanity in this character appealed to me, and I'll enliven the character in the drama". He also noted, "Currently we are bombarded with news of our entertainment world, but Jung In has complete control over his corporation, and creates entrepreneurial luster in creating stars.  Even as a guy, Jung In is very appealing." The first episode will air on November 11th, 2010.
