Along with fellow Beast member Junhyung, MC Lee Hyukjae, Moon Heejun (formerly of H.O.T.) and Kim Sook, Yang welcomed Japanese tourists for the "Visit Seoul 2010" campaign, where Korean celebrities and Japanese tourists explored Seoul through MBC's Star Guide Doshiraku to boost visibility of Seoul's famous landmarks and cuisine.[8] On July 16, 2010, Yang participated in the official soundtrack of the Korean drama More Charming By The Day as part of its promotional campaign, with the song "Happy Birthday".[5]

On November 29, 2010, Yang released a digital single together with Dalmatian's Daniel titled "First Snow and First Kiss". Both were friends from their trainee years at M Boat Entertainment and had released a UCC series, "To Pick On Mr. Daniel", which became a hot topic when it was selected as number one amongst the weekly TOP 5 UCCs by a sports newspaper.[4] He also became a permanent cast member on KBS' Oh! My School (a.k.a. 100 Points out of 100), along with other idols such as MBLAQ's Lee Joon, Secret's Hyoseong, T-ara's Soyeon, Miss A's Min, and Simon Dominic.[9]

Mother)", which helped silence the critics that had dismissed his singing abilities as just a hype.[12] However, on June 8, 2011, the show announced that Yang would leave the show due to his conflicting overseas promotions schedule with Beast.[13] 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."[12]

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.

On September 27, 2011, KBS' 'Poseidon' released part one of their original soundtrack series which featured Yang’s vocals. His song, "No", was a collaboration piece between Rado (of Huh Gak's "Hello") and production duo Ji In and Wontag, the men behind MBLAQ's latest releases. The song features sorrowful lyrics of a man who has no choice but to let go of his lover.[14]

Yang released his solo album on November 26, 2012. All five songs were produced by fellow band member, Jun Hyung, including the title song, "Caffeine". A music video for "Caffeine" was released two days later, on November 28. A music video for his song "Even then, I" was released on February 14, 2013, as a valentines gift for his fans.

Yang left I Live Alone in which he received much love as the youngest member of the show after a short six months on broadcast due to his responsibilities and schedules as a member of Beast.
