On May 13th, Block B and A Pink guested on MBC FM's "Younha's Starry Night" for an hour-long special filled with amazing live performances. Younha definitely had her hands full with having to host 14 rookie guests at once, but she managed to successfully pull it off all on her own. Since the two groups debuted in the same month just a week apart, Younha delved into some of the other similarities they also share. With the most obvious being that both groups are comprised of seven members, Younha also mentioned that each groups had pre-debut experience as well. Namju was a child CF model and Na Eun starred in B2ST's music videos prior to forming A Pink. Zico and Kyung promoted underground and released mixtapes, and Jaehyo was the star of an ulzzang cable program. Another similarity they shared was that they were backed by strong labelmate seniors.  As a member of the Cube family, A Pink revealed that they received a lot of great advice and support from 4minute, B2ST, and Huh Gak. Block B, although labelmates with prominent figures in the hip hop and reggae scene like Verbal Jint, Skull, and Rhymer among others, explained that they only receive professional advice and are pretty much left to fend for themselves in the wild, both in terms of their music production and growth.
