I also known as Chan Yoon Ji, the younger sister of B1A4's Baro, made her official debut with ''I Wish'' back in January.

She appeared on KBS2's 'The Unit' and hoped to make a debut in a girl group, but on November 24, she decided to give up on her dream and leave the show to focus on her health.

A statement was uploaded to her official fan cafe stating that I could no longer participate in 'The Unit' due to fatigue and health issues. She will be focusing on her health and recovery for now. She received a '6 Boot' as all the judges on the show gave her a boot and she was also the center of the female green team.

Here is the statement posted by her agency WM Entertainment, "Hi, this is WM Entertainment. Singer I has decided depart from KBS2's 'The Unit' program, she decided that she could not display her normal skills due to fatigue and other health-related issues. We appreciate your understanding of this difficult decision that was made. In the future, we will do our best for the full recovery of I. We hope everyone will continue to show their support for her and show a lot of love. Thank you."
