Yang Tae Seon is a member of the South Korean boy group TRCNG under TS Entertainment. They debuted with the EP New Generation on October 10, 2017.
Originally a ten-piece group, he and Jo Woo Yeop left the group in November 2019 and filed suit against TS Entertainment for violations of child welfare legislation, alleging abuse, assault, and extortion. They, in turn, were sued by the parents of the remaining members for spreading false information.
