On February 16 episode of tvN's television show 'On & Off', Choa talked about her departure from AOA in 2017.
Choa said, "I was a very positive person. So, I was totally fine with everything. But one day, it all fell on me. I couldn't continue living that life anymore."
She resumed, "It may be because I was lacking of sleep. I was just way too tired every day then. I think I needed some time off."

Choa answered, "For about a year, I slept and slept. I didn't get enough sleep when I was part of AOA, so I tried to get as much sleep as I could."
She continued, "During my time as a member of AOA, our staff members helped us a lot. After leaving the group, I realized I wasn't able to do much by myself."
She went on, "I started off by signing up for an online banking, then completed many tasks on my own. I learned to be more independent."

Recently, Choa opened her YouTube channel, and also returned to the industry.
