K-pop vocalist Yong Jun-hyung emerged as part of the key second-generation boy group Beast in 2009. Finding immediate commercial success, it wasn't long before the group's fourth EP, Lights Go On Again, debuted at number one on the Korean charts, followed swiftly by chart-topping albums Fiction and Fact (2011) and Hard to Love, How to Love (2013) along with number one EPs Midnight Sun (2012), Good Luck (2014), Time (2014), and Ordinary (2015). Throughout this period, Junhyung worked prolifically as an actor, reality TV star, producer, and solo artist, appearing on shows like Monstar, Coffee Do Me a Favor, and Hitmaker, and producing the entirety of bandmate Yang Yo-soeb's debut EP The First Collage. His solo career flourished with work alongside HyunA, Wheesung, and G.NA, as well as the 2013 solo EP Flower, which debuted at number four on the Gaon chart. In 2019, Junhyung announced his departure from the group, returning as a soloist in 2022 with the mini-album LONER.
