In January 2023, Primrose debuted as a duo with members Ruby and Yuem, releasing the EP Red Moon under the label AO Entertainment. However, Yuem had to leave the duo shortly after their debut due to health reasons.

Soon after, three new members—Rainie, Nahyun, and finally Hayun—joined, forming the “new” Primrose. In August 2023, they made their re-debut with the mini album Laffy Taffy, marking their first appearance on the Korean charts. The name Primrose comes from Latin and means “first rose.”

The name is meant to convey both gentleness and a rough side, as well as the idea of being the first to bloom. Their fandom name, “Prism,” symbolizes fans looking forward with their smiles toward the distant future. Prism is excited about the future of their band.
