The two also talked about how they were completely unlike each other. �As Jaehyun explained he was originally going to be an athlete, but turned towards becoming a celebrity, Jaekyung took over to explain how she used to be against it because she worried her sensitive brother would take negative comments too personally and get hurt.

When asked whether it was hard having an older sister in a girl group, he replied, "I have 300 older brother-in-laws."

Yoo Jae Suk said, "Jaekyung had said, 'Since I am ambitious, this is not the time to be dating a boyfriend,' and that she maintained this since youth."

Jaekyung said, "When I was a trainee, I had a grand dream to debut. �At the time I thought this was not the time to have a boyfriend. �However, after debuting, I realized I should have dated as much as I wanted before debuting. �I also advised my brother, Jaehyun, a lot. �I told him to date in secret without getting caught by his agency."

Jaekyung then bragged about how good of a brother Jaehyun was, saying how he didn't even have a picture of himself in his dorm, but a large picture of her. �She said, "My younger brother treats me extremely well. �When my birthday comes up, he makes his agency trainees write on rolling paper to give to me as a present. �That's how I even got happy birthday messages from�CNBLUE�members before their debut."

The MCs pointed out that most siblings fought a lot. �Jaekyung replied. "We used to fight a lot. �However, after I debuted, my brother respected me," making everyone laugh. �She even pointed out how he wouldn't wear clothes his mother picked out for him on the grounds they were tacky, but if he were told his sister picked them out, he'd say how cool they looked. �

"I debuted when my younger brother was a trainee," she continued. �"I think [he looked at me with respect] because he, as a trainee, realized how hard it hard and difficult it was to debut."
