The teaser image shows us just the feet with the caption 'For 7', leaving fans scratching their heads as to what it could possibly mean. 

Her agency kept their lips sealed on the meaning of the teaser, but regarding her concept, they stated, "Jiyeon's solo concept is like the 2014 version of the famed Park Ji Yoon's 'Adult Ceremony'... Jiyeon recently lost 5kg and is putting in effort to perfectly pull off her first solo track."

As previously announced, she'll make her debut with a title track by Duble Sidekick and choreography handled by Bae Yoon Jung on April 30, so we'll just have to wait for more teasers to figure out the mystery!
