R.ef Reveals the Secret Behind the Group Name

MBC "Come to Play" that was aired on Monday was 'Dance Dance Dance' Special.

Lee Sungwook and Sung Dehyun revealed that they set the group name first and labeled it 'Rave Effect' afterwards.

They added on, saying "there were other candidates such as invincible general, and phoenix but we didn't really like it. We had a hard time finding a good group name."

Sung Dehyun said "We saw Japanese TRF and it sounded really smooth. We plugged in all the alphabet and finally settled with R.ef."

On the other hand, on this episode of "Come to Play," DJ Koo, Cool, R.ef, and Koyote came out as a guest.
