Former AOA member Choa's appearance has changed a lot since her days in the girl group... is it the result of dieting?

Choa, a former member of the group AOA, has become a hot topic due to her unusual personality. On the 23rd, Choa posted on her Instagram, "My sister Sabe is always a good person.
He posted several proof-reading photos with the caption "Thank you #Isabe". In the photos, Choa is seen meeting Isabe and taking proof-reading photos while going on a date with her.
In particular, Choa caught the attention of fans as she appeared with a completely different look from her AOA days, perhaps because she had gone on a diet.
Meanwhile, Choa debuted as a member of AOA in 2012, and later left the group to become a solo artist in 2017.
She currently runs a YouTube channel called "CHOA" where she interacts with her fans.
