The title song “Psycho” from the finale of “The ReVe Festival” is an up-tempo urban pop song that combines a powerful 808 bass, rhythmical high-hitting sound with an ever-changing melody and an addictive hook that strongly showcases Red Velvet’s deft yet humorous vocals.

The lyrics talk about about two lovers who admit that their love is unique in the sense that although they hurt each other often to the point of parting, they always come back to each another. They only have each other as they’re perceived like psychos by the outside world.
