LC9 previously hinted at their comeback with photos of them at the studio with the mysterious hashtag #EOE, which might have something to do with the title of their upcoming digital single. However, this return will see an absence of two members with E.Den leaving for Canada to focus on his studies, and Rasa serving in the military.

Anticipation is running high for the group's long awaited return, so check out the short but sweet audio teaser above in the meantime!
