B2ST has been impressing fans with their latest hit, "Fiction," so it's no surprise that they were recently invited to perform on�Younha's 'Starry Night' radio show. On the radio show, B2ST performed their comeback track along with another song off of their popular album--"Fiction and Fact"-- called "On Rainy Days." In addition, they took a break from their singing to snap a couple of cute shots with Younha. We know how dedicated and talented these boys are and these performances are nothing short of spectacular. Check them out below! [gallery] Thanks to Mishii for the tip!
