During the 'Kiss My Lips' press conference on May 11, BoA brought up contributors Gaeko, who featured on track "Who Are You," and EXO's Sehun, who appeared in the MV for the same song.  

BoA said, "I had no mutual acquaintances with Gaeko, but I wanted somebody who could both sing and rap well.  I like Dynamic Duo's song, 'Guilty,' and the vocalist for that song was Gaeko.  That's why the company asked him for a favor."

In relation to Sehun, she said, "That was not my offer, rather the MV director suggested it. It was based on the thought that it'd be a big deal if there were a perfect man for a blind date."  If that was the criteria, than Sehun was definitely a good choice!
