K-Pop fans will soon hear another collaborative single involving a solo femaile artist in a winning combination with a popular rapper.

This time around it is After School member Raina and TROY's Kanto who will try to reach the top of the charts.

After School's Raina is going to release her first solo album 'Reset' on October 8, 2014.

For one of her singles, Raina revealed she recorded a track with Kanto. The single is titled, "I Know It's a Joke."

The message of this song is  about a woman who is in denial about the lasting power of her relationship.  The woman thinks that she will never get dumped by her boyfriend, but in the end, however, she does.

A representative from Raina's agency Pledis Entertainment said, "As much as this is Raina's 1st solo album, we worked hard to bring out Raina's real hidden vocals."

About the new single, the rep added, "Raina's vocalices and Kanto's baritone rap also helped bring out the song's lonely emotions. Please look forward to their chemistry."
