B2ST's Yoon Doojoon's sister revealed a childhood picture of her younger brother standing confidently before a mic through her personal Twitter. On January 25th, she tweeted, "It's been a while, this is Doodoo when he was little." The picture she uploaded alongside the tweet shows a younger Doojoon in the middle of giving a speech in front of a mic.�She added, "This was when he was six during church."�Doojoon amused fans by tweeting back, "Don't upload things like that, it's embarrassing." Fans commented in response, "Little Doodoo, his face is exactly the same," "He liked mics since he was little," and "He's so cute, I want to bite him!" The nickname of "doodoo" might be a bit more�embarrassing�to English speaking fans, but it's adorable nevertheless. Meanwhile, B2ST is currently preparing for their two-day encore concerts scheduled for February 18th and 19th. Source: Star News via Nate
