Male vocal group Noel's Kang Yoon Sung recently shared the difficult times he had gone through at the time of Noel's 3rd album release.

The singer guested on the April 21st broadcast of MBC's 'Quiz That Changes the World' and revealed his difficult past. "Back in 2006, I signed a solo contract with JYP Entertainment,�but it quicky ended up as if it didn't exist. Noel wasn't doing well at the time, so the idea of me releasing a solo album was taken negatively from the public."

He continued, "I was hurt knowing that the contract was handed over to a different company. However, I believe that Jinyoung hyung didn't make a bad decision." When asked whether he still keeps in touch with J.Y. Park, the singer sternly denied.

Others that guested on this week's episode were Hwang Soo Kwan, Jo Kyung Hwan, Lee Gae In, Ko Young Wook, and more.
