Red Velvet sings a serenade to fans. To commemorate the 10th anniversary of their debut, they are releasing a fan song.

SM Entertainment said on the 25th, "Red Velvet will release the new song 'Sweet Dreams', which will be the epilogue to the new album 'Cosmic', on the 1st of next month."

On the 10th anniversary of their debut, they sing a message of promise to their fans. ‘Sweet Dreams’ is Red Velvet’s fan song. It is a warm good night greeting from the members to the fans who have grown up together for 10 years.

It is a medium tempo song. It features a cheerful melody and half riff using the arpeggio technique. The lyrics describe an imaginary friend (doll) who wakes up inside a bookshelf at night and stays by your side.

It contains sincere thoughts toward Red Velvet's fans. An official said, "The message was that we who dream the same dream will always be together and share endless stories."

A new version of the 'Cosmic' album containing new songs will also be released. The album will also be released on the same day. You can also find components using the members’ characters. The sound source will be released at 6 PM on this day.

Red Velvet is preparing for their fan-con tour. ‘HAPPINESS: My Dear, ReVe1uv’ will be held at the Seoul Olympic Handball Stadium from August 2nd to 4th.
