B2ST's Lee Ki Kwang recently suffered a humiliating blow after it was revealed that only 5 cast members on KBS's "Happy Birthday" knew that he had a solo career. Ki Kwang was previously known as 'AJ' before his B2ST debut. On this week's episode of "Happy Birthday", Ki Kwang and fellow member Junhyung shared that Cube Entertainment was not the first agency they signed with, and that they went through countless auditions before landing a contract with Cube. "I used to promote as a solo artist, but I failed", said Ki Kwang. Junhyung added, "There was a time when I was a back dancer for Ki Kwang, too." To this, Lee Soo Geun asked, "Is there anyone here who knew Lee Ki Kwang came out as a solo?" A total of 5 members on the set raised their hands - Seo In Kook, Yoon Hyung Bin, Choi Sung Won, Seon Woo, and Jung Kyung Mi. Surprised, Lee Soo Geun then asked, "Why did you fail when this many people knew about you?", but Choi Sung Won intercepted with his wit as he joked, "Is it because only these 5 people knew about him?", causing the whole set to burst into laughter and avoid a possibly awkward situation.
