B2ST's pre-release track "Butterfly" took first place on music charts!
Regarding this, B2ST said on the same day to OSEN, "Firstly, we're extremely happy. We were already happy at providing new content to our fans and seeing them happy about that, but we even got first place on music charts, so we feel like our happiness is soaring like a 'butterfly.' Even in the future, we won't lose the heart we have now, and will work hard in order to do music for our fans and dedicated to our fans. Thank you."
