B2ST appeared on 'Yoo Hee Yeol's Sketchbook' on July 22!

On this day, Doojoon chose their early song "Mystery" as the most grateful as well as embarrassing thing.  He explained, "After our first concert, we never [performed] that again. I wondered how we could have survived in the music world with this dance."

Junhyung agreed with, saying that he could not fathom how they did the dance during their debut days, yet they worked diligently.  They performed the song on the show after which Yoo Hee Yeol asked, "Does this dance really exist?"

Doojoon was also asked why he's the only member not to write lyrics and replied, "That's not my domain.  I'm in charge of vitality and energy in the group.  I will stick with that."
