Park Kyung was originally excluded from Block B. 

On the January 31 airing of SBS' 'I'll Win You Over With My Channel,' P.O. shared the story behind Block B. 

He revealed, "The initially confirmed members for Block B were Zico, U-Kwon, Jaehyo, B-BOMB, and Song Min Ho."MC Kang Ho Dong asked, "How about Kyung?" P.O. replied, "Kyung hyung was eliminated."

He explained, "Kyung hyung was studying in New Zealand but he came back to Korea because Zico hyung told him to. Originally, the two were the main figures behind Block B." However, "The agency didn't like Kyung hyung. He was short, his visuals weren't that good, and he was so talkative so they didn't really like him."

Kang Ho Dong asked, "He was best friends with Zico. Couldn't he just become a member through Zico's recommendation (to the agency) or did Zico oppose too?" P.O. and Song Min Ho brought laughter as they refused to answer for the benefit of their friendship.
