Early life and training
JEONG WOO joined a vocal academy and auditioned for YG almost immediately, then competed on YG Treasure Box. His raw vocal ability was obvious early; the training story is about learning how to place that voice inside choreography and a very large team.
The common mistake is to compress every TREASURE member into “survival-show trainee.” The show was the public gate, not the entire education. Training length, starting skill and the reason each member stayed visible were different. For PARK JEONG WOO, the useful thread is continuity: the qualities visible before debut are still present, but they now carry the weight of six years onstage.
Career
Pre-debut · earning the lineup
YG Treasure Box asked trainees to compete across vocals, rap, dance and audience response. The final plan changed repeatedly—from separate TREASURE and MAGNUM units, to TREASURE 13, to one twelve-member group—but PARK JEONG WOO remained part of the project that finally debuted.
2020–2021 · The First Step
TREASURE debuted with “BOY” on August 7, 2020 and released the First Step series at unusually fast speed. These stages established PARK JEONG WOO’s base identity before the group had enough songs to specialize.
2022–2023 · ten-member reboot
After MASHIHO and BANG YE DAM left in November 2022, the group reorganized as ten. REBOOT and its units gave the remaining members more space, more credits and more responsibility. JEONG WOO’s job has stayed consistent across lineup changes: supply the vocal event. As TREASURE moved through brighter pop, heavier YG tracks and the sparse NEW WAV sound, his presence kept the group from becoming rap-heavy in a way that erased its singers.
2024–2026 · chapter two
Singles, PLEASURE and LOVE PULSE led into NEW WAV, the 2026 all-hip-hop mini album. Read the connected review of “IF I” for the current ten-member sound, formation work and rollout tea.
Skills and stage identity
He is one of TREASURE’s clearest power vocalists. The tone is full, emotional and especially useful when a chorus needs lift rather than another rhythmic phrase. Live stages are where the argument for him becomes easiest.
What to listen for
Find the moment the arrangement gives PARK JEONG WOO room rather than counting lines. In a ten-member song, impact matters more than raw seconds. Tone, timing and what happens immediately after the part tell you why it was placed there.
What to watch
Watch transitions and reaction shots, not only center time. TREASURE’s large formations depend on members remaining active when the camera is technically pointed elsewhere. PARK JEONG WOO’s value often becomes clearest in that connective work.
Era map
| Era | Why it matters here |
|---|---|
| The First Step | Debut identity and the original twelve-member scale. |
| “JIKJIN” / “DARARI” | The split between YG-force performance and TREASURE’s softer viral side. |
| REBOOT | Ten-member redefinition, larger individual roles and unit work. |
| PLEASURE / LOVE PULSE | Fan-facing warmth, self-production and the road into chapter two. |
| NEW WAV | All-hip-hop framing, current leadership and the English title track “IF I”. |
Fandom file
Offstage he is loud, competitive and easy to provoke into a bit. Onstage the focus tightens. That switch is why casual viewers who know the funny clips are often surprised by the seriousness of the voice.
The RaeRae take
PARK JEONG WOO matters because the big-voice vocalist who can turn one ad-lib into the emotional plot. The page is not here to hand out a bias rating or reduce a person to three trivia bullets. The point is to show what changes when this member enters the song, the formation or the room.
The next step is evidence: every new TREASURE MV review will link back here with the exact vocal, rap, dance, writing or performance moment that belongs to PARK JEONG WOO. Profiles should get deeper as the review library grows, not sit untouched after publication.
