On the February 16th airing of KBS CoolFM's 'Jang Dong Min & Lady Jane's 2 O'Clock', 4minute revealed the reason why the members don't have many idol friends, while HyunA explained the difference between promoting alone versus with her members. 

To start off the conversation, the two DJs asked HyunA what her thoughts were on promoting alone versus with 4minute members and what she prefers. HyunA  said, "I am more comfortable working in a group. When I promote with 4minute as a whole, it's as though I am wearing my own clothes." 

DJ Jang Dong Min then asked, "Even then when it comes to income, isn't it better to work alone?" HyunA responded, "No. There's actually more that goes into solo promotions [than group promotions]. It's harder when I don't split [the income]."

In addition to HyunA's thoughts on working as a group, members of 4minute confirmed their close relationship with each other and revealed that not many idols greet them because of their personalities.

DJ Lady Jane asked the girls, "You guys are known for being very close with each other. Are you not close with any other idols?" Jihyun then responded, "They don't really seem to talk to us." 

DJ Jang Dong Min also asked, "Do you think it's because of your strong-unnie concept?" The 4minute members answered, "We get shy when it comes to greeting others. It may be that we don't affectionately accept greetings from younger idols, but they don't greet us first anymore."
