Recently, on Daum Yozm (a microblogging platform similar to Twitter and me2day), B2ST's Hyunseung posted an old picture of himself with his sister.  He wrote: "How are you spending your New Year's?  ^^I ate a lot of delicious food, gained some weight~ You all should cheer enthusiastically during the concert!!!!  The picture was taken with my younger sister when we were kids~kekekekek dad took it^^ Wow, how cool were we?" The two certainly look like they mean business! Source: Hyunseung's Yozm Tip: pakuuman
