[talk] Doyoung's new single, Promise, is great to listen to in the winter.

This single is said to contain the feelings he wants to convey to his fans.

Just by looking at the description, you can feel Doyoung's unique warm atmosphere.
The title song "Promise" is even better because the lyrics were written by Doyoung himself.

The track Whistle is said to have been sung with Belle, so the combination itself is already sweet.
