G-Friend appeared on SBS powerFM's 'Kim Chang Ryul's Old School' on January 28, where SinB revealed which girl group's concept she personally wanted to try out next.

When asked about their next album concept, they replied, "For now, we like our concept right now," but mentioned hip hop and others.  DJ Kim Chang Ryul promised, "If you do a hip hop concept, I will invite you to our concert as guests."

Known to be the sassy and tough one of the group, SinB stated, "I want to try a bit of a strong, 'girl crush'-evoking concept.  For example, I want to do something like f(x) would do."
