On the May 17 broadcast of 'Channel AOA,' there was much discussion over ChoA's eating habits and weight maintenance!

The girls first talked about ChoA during the girls' training days, Mina saying, "ChoA eats well. After practice, she always would buy and eat a bagel."  Hyejeong added, "ChoA was like a mother."  Jimin said, "ChoA is AOA's supportive crutch."

Also, the topic of devil's tongue jelly came up.  Looking at the food, ChoA and Jimin said, "We had to maintain our bodies when we were training.  We learned of devil's tongue jelly and ate it."  ChoA continued, "We heard that after eating it, the devil's tongue jelly will expand to thirty times its size inside your body," suggesting the girls ate it to curb hunger. Jimin then revealed, "Because ChoA and I ate a lot of the devil's tongue jelly, we once were even taken to the emergency room the next day." Be more careful with what you eat!

Also on this day, ahead of their comeback on May 17, ChoA can be seen exercising while the other members were taking a rest.  At this time, Jimin appeared and ChoA said, "It's our comeback but I gained too much weight."  She started working very hard on the bike, and seeing this, Jimin played the reset button covertly to prank her, causing laughter.
