Lee Chae Yeon revealed why she and her younger sister ITZY's Chaeryeong used to fight.

On the October 17th YouTube episode of 'Studio Waffle', Lee Chae Yeon opened up about her relationship with her sister Chaeryeong. The former IZ*ONE member shared the reason behind their fights, saying, "Are those your socks or mine? Don't copy my nails. We would fight a lot over things like that. There was even a time we grabbed each other's hair. We fought each other in front of a math academy and didn't let go until the other did." However, Lee Chae Yeon said things have changed since then, expressing, "Our relationship got so much better after we debuted." 

As for their ideal types, she said they have the opposite taste in boys, saying, "I like guys who look like dinosaurs these days." Jo Se Ho also asked Lee Chae Yeon if she would rather date her younger sister's friend or her friend's younger sibling, and she responded, "Because I'm the eldest daughter, I don't want to be caught in a relationship like that."
