Jongseob was born in Paju, South Korea, on November 19, 2005. While details about his early childhood remain private, his path to stardom began with a significant step into the entertainment industry during his middle school years.

His participation in The Unit eventually led to his selection as a trainee at FNC Entertainment. During his training years, Jongseob honed his vocal abilities, rap flow, and dance techniques. The road to official debut was paved by the reality show P1Harmony: The Debut, which aired in 2020. This survival-style series followed the lives of seven finalists competing for a spot in the new group. Jongseob emerged as one of the final seven members selected to represent FNC Entertainment, marking the end of his pre-debut journey and the start of his professional career. [edit]
