We reported earlier that a full-length music video for KBS2TV's new drama, Cinderella's Sister was in the works and it would be featuring the vocals of Super Junior's Yesung. And just one day away from the actual broadcast, the full-length music video has finally been released and if you thought the teaser photos released in the past few weeks were intense, you ain't see nothing yet. Together with the vocals of Yesung (who is a big fan of Moon Geun Young), the drama looks like it's going to be a smashing hit. http://www.youtube.com/watch?v=FeWCb3llsVo With the exit of the ratings monster Chuno last week, the Wed-Thus timeslot will for the first time in months see competing dramas from MBC (Personal Taste), KBS (Cinderella's Sister) and SBS (Prosecutor Princess) start together. With the exception of Cinderella's Sister which is likely to be a thriller, the other two are romantic comedies. It will thus be interesting to see which drama will rise to the top after their first 2 episodes! What will you be watching on March 31st?
