‘It Has To Be You’, as aggerated by SK Telecom (up to April 13th), reached number one on both Ringtone general chart and Ringtone weekly chart, said a representative from SM Entertainment.

The song, with the deep, touching voice of Super Junior member Yesung, accompanying the drama’s characters’ real emotions, has caused a great sensation.

With the love story amongst four characters in ‘Cinderella Sister’, spectacular scenes and beautiful music, as well as a full music video in which drama scenes and music are perfectly hamonized, ‘It Has To Be You’ is expected to gain more popularity.

Super Junior Yesung is also known for having sung the original soundtrack for SBS drama ‘Tazza’ – a ballad song which received a lot of affection.
