Super Junior's Choi Siwon and Donghae have been cast in the Taiwanese drama Extravagant Challenge as the leading male roles. According to Taiwan iFensi on the 24th, "The decision to cast Choi Siwon and Donghae into Extravagant Challenge has been finalized." Extravagant Challenge is a remake drama of a Japanese comic called Skip Beat, and it's about a girl that gets betrayed by her long time boyfriend. In an attempt to get revenge, she debuts as a celebrity, and the drama unfolds with the various events she experiences soon after. Taiwanese actress Lin Yichen will be playing the leading female role for the drama. Choi Siwon and Donghae already appeared in her music video for Firefly last September, and that was how the two were brought up during casting discussions. Choi Siwon's character is a successful celebrity that chooses business over his girlfriend. Although he is able to capture the hearts of women with his charismatic looks, he often looks back on his memories with his innocent girlfriend. Donghae will be playing the role of a top star, and he is regarded as having the best looks and acting skills in the industry. He is also a mysterious figure of the leading female's childhood, having disappeared when they were both young. This will be Donghae's first time acting, so much attention has been put on whether he will be able to express a character with perfect looks but awkward emotions. Extravagant Challenge will begin filming in March of next year.
