[talk] Doyoung released his new single Promise the day after his enlistment.

Doyoung is finally ready to shake fans' hearts with his new single, Promise, the day after he enlists.

This single contains two songs, the title track "Promise" and "Whistle" (Feat. Bell of KISS OF LIFE).

They say they prepared it specially to express their gratitude to their fans.

It was a more meaningful release because it was right after his enlistment, so the album was also released on the same day.

The warmth and emotion conveyed through Doyoung's voice can be fully felt through this single!
