MEMBER PROFILE
Jagger
Lead Rapper, Sub Vocalist in SEVENTOEIGHT.
Profile
SCOOL ranking and final selection
Jagger entered SCOOL as Chen Bai You, one of the Taiwanese contestants in a program jointly built for Korean and Taiwanese promotion. He finished fifth in the final ranking and secured a place in the debut team. The result matters because it documents the public-selection route into SEVENTOEIGHT rather than treating the group as if it appeared fully formed in 2025.
His theater background gave him a useful starting tool. Survival-show stages require a contestant to communicate a role quickly, often with limited lines and rapidly changing camera assignments. Theater does not automatically make someone an idol rapper, but it helps explain why expression and projection became recurring parts of Jagger’s performance identity.
Lead rap and supporting vocal work
At SEVENTOEIGHT’s debut showcase, Jagger was presented in the lead-rapper and supporting-vocal lane. “PDSR (Please Don’t Stop the Rain)” emphasizes melody and a softer emotional atmosphere, while “DRIP&DROP” uses stronger rhythmic accents and performance pressure. Moving between those tracks asks him to support the group’s blend in one setting and sharpen the song’s edge in another.
His job is easiest to see in transition sections. Watch how he changes facial intensity before a rap entrance, keeps his steps connected to the formation, and exits without making the next singer rebuild the song’s mood. That handoff work is part of good group performance even when it is less obvious than a center shot.
A Taiwanese member debuting through Korea
SEVENTOEIGHT is unusual within K-pop because its six-member lineup is built from Taiwanese and Malaysian performers rather than Korean members. KBS World’s debut coverage described the members’ excitement, language pressure, and continued musical and Korean-language training. Jagger’s profile therefore belongs inside both Taiwanese pop and Korean idol contexts.
The group name and fandom language also preserve that cross-border identity. Their work is released through Korean stages and distribution while the team continues to communicate with Mandarin-speaking audiences. Jagger’s theater experience and vocal-rap flexibility are useful in a career where interviews, fan events, and performances may shift languages and presentation styles.

Member profile, not a duplicate Artist page
This is Jagger’s single canonical person profile. His documented releases are currently group and program work, not a formally promoted solo music catalog. He therefore belongs in the Member directory and should not appear in Artists unless an official solo career begins. Interviews, personal social accounts, and individual performance clips can expand this page without creating another identity.
YouTube tracking history
CVM Sekai tracks SEVENTOEIGHT’s official channel for music videos, dance practices, performance footage, behind-the-scenes releases, and clearly credited Jagger content. The same group release may be attached to the SEVENTOEIGHT page and this member profile so fans can find it from either route without duplicating the person.
Before SEVENTOEIGHT
Jagger came into SCOOL with theater experience and a reputation as a strong student. Theater is useful training for an idol rapper because the job is not only delivering rhythm. It is making a line readable from twenty rows away while a camera moves past your left ear.
SCOOL
Jagger competed on the Korean-Taiwanese survival show SCOOL and earned a place in the final team. Survival shows love to compress years of training into one dramatic ranking. The profile matters because the person did not begin when the cameras did.
SEVENTOEIGHT debut
The group pre-released “PDSR (Please Don’t Stop the Rain)” before debuting officially with “DRIP&DROP” on July 28, 2025. Jagger entered a six-member active lineup with Chiwon, M, EXXI, Kyojun, Jagger, and D’om. The group promotes from Korea while keeping a strong Taiwan-based identity.
Jagger knows that rap delivery has a face. He does not throw expressions at every syllable, but he gives the group a sharper edge when the debut song starts feeling too polished.
