B2ST have been successfully capturing the hearts of their B2UTY fans for the past few weeks with their new title track, 'Beautiful', from their recently-released 4th mini album. On this week's episode of Music Core, B2ST were able to have a special stage to kick start the countdown until Christmas. Their sweet love song matched well with the Christmas spirit, and they performed with their utmost energy and excitement. Check out their outdoor theme park performance below!
