Super Junior’s Yesung is lending his vocals for the OST of MBC’s new drama I Do I Do. Yesung will be singing the main theme song of the drama’s main male lead, Park Tae Kang (Lee Jang Woo). The song is titled Her Over Flowers and straightforwardly expresses the feelings of a man who is in love with an older woman. The light and cheerful tune is expected to be accentuated by Yesung’s smooth vocals. A source close to the drama production said, “We believe the song will more than adequately add to the fun and emotional depth of the drama.” Her Over Flowers will be unveiled online on May 31. I Do I Do airs every Wednesday and Thursday nights on MBC.
