On May 3rd, rookie boy group B1A4 kicked off a week of their first radio broadcast guesting on MBC's "Park Kyung Lim's Starry Night." "Starry Night" features a seven-minute corner for rookie groups to guest in and show off what they've got in seven minutes. The corner is set up so that groups can perform one live track and go into introducing their profiles to listeners. B1A4 stunned with their live performance of their debut track, "OK", and adorable gestures towards the live camera. MC Park Kyung Lim teased the boys about their name, claiming that it reminded her of a parking lot. Leader Jinyoung was up first for the round of 'profile talks' and sang a short snippet of "Bling Girl", the song he participated in writing and composing. Unfortunately, the bell signaling the end of their corner went off just then, but fans can expect more fun performances and the rest of their profile talks on the 4th and 6th.
