G-reyish (그레이시) is a four-member girl group under Elijah Entertainment. They debuted on June 1, 2017 with the single “Turn Back Time”.
Their group name was inspired by the color gray. Since gray won’t lose its original color – even when mixed with other colors – the girls hope to be a group who won’t lose their original color. The group doesn’t have a set leader.
