"It's impressive A Pink members didn't have a single dating scandal during their 12 years of career."

"EXO really has been in their prime for a decade." 

"BTS is the group that has all three good records, big fandom, and popularity. So impressive." 

"BTS still is writing history. And they are already a 10 years old group." 

"SHINee is a 15 years old group and all the members are still staying with the group. That's something."
