[Picture] CN Blue's Jung Shin and A Pink's Namjoo pose together!

I am still in th process of memorising A Pink's member's name and this photo is undoubtedly a huge help for me.

Managed to memorise another A Pink's member's name,Namjoo posed with CN Blue's Jung Shin at the backstage on Music Core earlier today,i have seen comment saying that they look like siblings here,any opinion to share?
