On the September 1 airing of MBC FM4U's 'Kim Shin Young's Noon Song of Hope,' LABOUM made an appearance and talked about fellow celebrities with whom they went to school!

On this day, DJ Kim Shin Young said, "I heard that ZN was famous for her looks along with Seolhyun."  Looking timid, ZN replied, "I was the 'truth (Jin)' in the 'truth, good, and beauty (Jin-Sun-Mi)' back at school.  Seolhyun was the 'good (Sun).'"

Soyeon then brought up her close friend, Suzy, saying, "We were best friends while in elementary and middle school.  We often went to karaoke, and while the other kids rapped or danced, only the two of us would sing solely ballads."

The DJ asked if she contacts Suzy often, and Soyeon replied, "I don't have a cell phone yet, so I'm unable to contact her often, but I phoned her a couple times.  Also, when Suzy promoted our new album, her influence was amazing."
