One lucky fan picked up and immediately recognized the B2ST members' voices. She answered even the most random quiz questions thrown at her correctly proving herself to be a big fan, impressing the members. Also like any fangirl, she couldn't hide her squeals and screams as the boys called her name and spoke to her. Unfortunately this couldn't be said for the other fan they called, who immediately hung up on them assuming the members to be prank callers!
