On May 20th, B2ST guested on KBS FM's "Super Junior's Kiss the Radio" and performed their two comeback tracks, "Rainy Days" and "Fiction" plus their "Beautiful" track. The boys proved that they didn't need a fancy spotlight to stand out, as they did just that with�their vocals alone (and in casual attire to boot!).�If you missed their appearance on last week's show, be sure to check out their pictures below as well.
