IZ*ONE's Chaeyeon shared about her sister's debut. 

On April 2, Chaeyeon, Jang Won Young, Honda Hitomi, and Choi Yena guested on SBS Power FM's 'Choi Hwa Jung's Power Time.'

During the radio show, Chaeyeon talked about her sister, Chaeryeong, making her debut in the new JYP Entertainment girl group ITZY. 

Chaeyeon said, "When Chaeryeong debuted, I was happy as much as the time I made my debut in IZ*ONE." She added, "We grew more intimate because we're away from each other for a long time," and shared, "My parents love it. My dongsaeng wrapped up promotions, then I made a comeback so they were able to see us back to back." However, "They say concerns have also doubled."
