Mother)", which helped silence the critics that had dismissed his singing abilities as just a hype.[14] However, on June 8, 2011, the show announced that Yang would leave the show due to his conflicting overseas promotions schedule with Beast.[15] He expressed that although he felt extremely stressed competing against his peers, he felt regret having to leave. Yang said "when we decided on the withdrawal, I did feel some relief. It was too nerve-wracking and burdensome. However, at the same time, I felt regret. I don't think I was able to show my all. If another opportunity came by to be on the show again, I would definitely take it. I think I will. I want to show different sides of myself."[14]

Yang was featured in Bang Yong-guk's first solo track, "I Remember" which was jointly composed by Bang and One Way's Chance. The track has gained a lot of interest from netizens and become a hot topic. Yang was not able to sing "I Remember" with Bang Yongguk live.
