Previously in early December, FCENM Entertainment announced that “Girls Planet 999” contestants Kishida Ririka, Hayase Hana, Chang Ching, and Lee Yun Ji would be debuting in their upcoming six-member girl group. However, on January 5th, the agency confirmed that the new girl group would debut sometime in March and that the group name will be "ILY:1".
"'ILY:1' is a combination of the word “I” and the suffix “-ly,” meaning “like I” or “like myself,” while the “1” represents the individual members with their unique characteristics coming together as one group. It also carries the additional meaning of the acronym for “I Love You,” representing the group’s love for their fans. The name is pronounced “eye-li-one.”'
