While she is said to be good at everything, she once caused a stir by forgetting the choreography... There was an employee exposé claiming she scowls whenever she sees one specific male idol from the same agency, but public opinion shifted to "that's understandable" once it was revealed he is her biological older brother. At the time of her debut, many said she looked like Fantasia's Kang Baek-yu (the brother), but after appearing on self-produced content with their mother, it was revealed they just have incredible genes. They are known as the legendary celebrity trio (she also has an older sister).
