Jung Jae Won, better known by his stage name One (stylized as ONE), is a South Korean rapper, singer, songwriter, and actor. He debuted in 2015 as a member of the hip-hop duo 1Punch with Samuel Kim but later One moved to YG Entertainment from D-Business Entertainment, following the group's disbandment in September that year because he was scouted by YG Entertainment and they offered him an exclusive contract. In 2019, ONE has announced his departure from YG Entertainment and his plans to establish his own one-man agency. In 2016, he also made appearances in the music videos for MOBB's "Hit Me" and Lee Hi's "My Star". It was reported that he became the first male solo artist to debut from YG Entertainment in 14 years since Seven's debut in 2003. (Source: Wikipedia) Watch drama online for free.
