SECRET has been in the spotlight lately with their win on M! Countdown as well as many overseas love calls. On top of that, their album sales are also going well. On January 21st, SECRET's management company TS Entertainment expressed, "SECRET's new single 'Shy Boy' has sold all of the initial shipment, and we have been working all night to meet the demands of additional volumes. The album sales are exceeding our expectations. It's a shame that we couldn't provide enough copies to music stores, but we will deliver more supplies as soon as possible." SECRET's increased popularity has even been coined as the 'SECRET wave'. On the other hand, the dance rehearsal video for "Shy Boy" was released recently.
