Girl group 4Minute's member HyunA revealed that her group is all very shy with people they're not close to so they don't have many friends.

In Mnet "Beatles Code 3D" aired yesterday, groups 4Minute and Toheart came out as guests.

HyunA was asked, "Why doesn't 4Minute have friends?" and she answered, "At first, people heard that 4Minute is very shy at first so they took the effort to approach us first. But after a while, they got tired and stopped trying."

Key also said, "We once practiced with 4Minute. They didn't say a word to us even though we were preparing for the same stage together."
