Biography and career file
Pre-debut: before ARrC, the classroom voice that escaped into the algorithm
Before Mystic Story introduced him as Ziwoo, Kim Ji-woo already had a public voice. He appeared on I Can See Your Voice 10, and a classroom clip of him singing Mark’s “Marry Me” reportedly collected millions of TikTok views. The clip worked because it did not look engineered: a student, a familiar song and a voice too finished for the room.
Virality is not training, but it changes the starting line. Ziwoo entered Mystic Story’s incubation camp in June 2024 and debuted with ARrC two months later. Like Doha, he arrived close to the official launch. Unlike a completely unknown trainee, he also carried an existing audience expectation: the boy from the classroom video had to become a main vocalist inside somebody else’s concept.
The original main vocalist
Ziwoo debuted on August 19, 2024 as ARrC’s main vocalist. His tone gave the original lineup a clear melodic center and a little emotional gravity beneath its youthful hip-hop styling. “S&S (sour and sweet)” needed the rap structure to feel energetic, but it also needed a voice capable of making the sweeter half sound like more than a branding word.
He was not in ARrC long enough for the role to develop across multiple eras. That makes his original-lineup footage important. It documents the first vocal architecture of the group before January 2025 forced everyone to learn a revised version.

January 22, 2025: departure without a public autopsy
Mystic Story announced that Ziwoo would leave ARrC for personal reasons on January 22, 2025. The company also explained that pre-filmed content might still include him. That second sentence was necessary because fandom timelines are not production timelines. Videos can be recorded weeks or months before publication, and a person appearing after a departure notice does not automatically reveal a conspiracy.
“Personal reasons” is unsatisfying because it does not let fans solve the story. It is also a legitimate boundary. Ziwoo was eighteen. A profile can document what happened without inventing the private chapter he did not publish.
Jiwoo: the solo return
In March 2026, he returned under the simplified stage name Jiwoo with STAY IN THE MIRROR through 5SECONDS Entertainment. That return changed the meaning of the departure. He had not vanished from music; he had left one structure and rebuilt inside another.
The solo file lets listeners compare three versions of the same instrument: the viral classroom singer, the ARrC main vocalist and the artist expected to carry an entire release under his own name. The voice remains recognizable, but the responsibility changes. A group line can be a bright window. A solo song makes the singer build the house around it.
One person, two searchable roles
Ziwoo belongs on the member directory because he is part of ARrC’s original history. Jiwoo belongs on the artist directory because he has active solo work. Those are tags and views, not duplicate humans. Keeping one canonical profile protects the timeline, the internal links and the SEO trail while letting fans discover him through either chapter.
That structure also prevents a common fan-site failure: the solo artist page pretending the group never happened while the former-member page stops at the departure notice. His story only makes sense when both halves can see each other.
The panda side quests
- Family café: early profiles called him the café’s CEO, which may be the most K-pop possible promotion from “helps with the family business.”
- Voice comparison: classroom clip, ARrC stages and solo recordings form a built-in vocal-growth playlist.
- Stage-name edit: Ziwoo in ARrC, Jiwoo as a solo artist. Same person; fewer SEO duplicates.
- Privacy boundary: leaving for personal reasons does not make the fandom entitled to the missing document.
- Timeline detective work: pre-filmed content teaches the useful lesson that upload dates are not filming dates.
Fandom notes and things the fact box misses
- Birth name: Kim Ji-woo (김지우).
- ARrC status: original main vocalist from debut through January 22, 2025.
- Solo status: active as Jiwoo from 2026.
- Viral origin: the “Marry Me” classroom clip and I Can See Your Voice 10 predate ARrC.
- Pre-filmed footage: not evidence that the departure was reversed.
- Canonical rule: former member and solo artist belong to one profile, with both directory tags.

Ziwoo does not currently have a verified standalone official solo-video catalog. His former ARrC group releases remain attached to the ARrC group profile so group totals are not duplicated as individual activity.

Where Ziwoo fits in the ARrC timeline
Ziwoo belongs to ARrC’s original seven-member chapter. His departure was announced on January 22, 2025, before Andy joined the lineup and long before the “awesome” release. That means a useful archive must resist the lazy habit of attaching every later ARrC file to every person who ever held the group name. Ziwoo helped establish the debut-era identity; he did not participate in “awesome,” and this profile does not pretend otherwise.
The overlap in promotional footage can still make the timeline look messier than it was. Companies prepare content ahead of release, schedules cross, and an image can remain visible after the lineup has changed. The clean way to follow Ziwoo is through the original-era catalog and the lineup-change Tea file, while the final seven-member “awesome” material stays attached to Hyunmin, Kien, Choi Han, Andy, Rioto, Doha and Jibeen.

Current status: the solo return changes the former-member file
Ziwoo did not remain frozen in January 2025. Returning in 2026 under the name Jiwoo turns this from a simple departure profile into an artist transition: original ARrC main vocalist, then an independent identity with new work that must be tracked on its own terms. That does not erase the group chapter, and the group chapter should not swallow everything that followed it. The useful profile is both a member archive and an artist file.
This is also why “former member” cannot become a synonym for disappeared. Fans often lose people at the exact moment company channels stop making the path obvious. A durable archive keeps the confirmed departure, original-era performances and later solo work connected without pretending the timelines overlap. Ziwoo’s ARrC footage explains where many listeners first heard him; Jiwoo’s solo activity explains why the story continues after that footage ends.
The departure file has a boundary
Mystic Story announced on January 22, 2025 that Ziwoo left ARrC for personal reasons and warned that prerecorded material might still include him. That is the full official explanation. A profile can acknowledge how abrupt it felt without inventing a health diagnosis, conflict or punishment to make the silence more satisfying.
Production timing explains why participation cannot be assigned from upload date alone. A video published after departure may contain earlier footage; a later comeback does not belong to him simply because the channel still carries his face in older thumbnails. Exact credits and recording context decide the relationship.
Ziwoo’s ARrC chapter therefore covers the original lineup through his confirmed departure. “awesome” belongs to the final lineup with Andy and does not attach here. This is not erasure. It is the accuracy that prevents former members from inheriting work they did not perform.
STAY IN THE MIRROR makes Jiwoo an active artist
Jiwoo returned on March 13, 2026 with the single “STAY IN THE MIRROR” through 5SECONDS COMPANY, distributed by Warner Music Korea. The official YouTube artist upload credits him as vocalist and co-lyricist with Woosoo, with Woosoo and Solshine composing and Solshine arranging.
That co-lyricist credit matters. The song is not merely a company testing whether the former idol can carry a melody alone. Jiwoo helps shape the language of a debut about love, anxiety and questioning the self reflected back. The mirror concept could have become decorative sadness; authorship makes it part of his artist file.
The release includes the title track and instrumental, running just under six minutes as a single album. Short catalog does not mean no catalog. The old sentence claiming he has no verified solo-video history is wrong and must be retired from both prose and tracker logic.
Three versions of the same voice
The classroom “Marry Me” clip introduced a voice outside professional framing. ARrC placed that instrument inside rap-heavy group arrangements where a main vocalist supplied melodic center. “STAY IN THE MIRROR” asks it to hold an entire emotional structure without six other identities sharing the load.
That comparison is more useful than pretending the solo release proves the group constrained him or that ARrC was only preparation. Each setting asks different work. Viral singing rewards immediacy, group singing rewards contrast and continuity, while solo recording requires the voice to establish its own world.
Listen for how Jiwoo handles space. A solo R&B/pop track can leave more air around the phrase than ARrC’s crowded youthful production. Breath, vowel length and restraint become audible decisions rather than gaps between rap sections.
One canonical person, two directory routes
Ziwoo remains in the member directory because he helped build ARrC’s debut lineup. Jiwoo belongs in the artist directory because he now has an independently credited release. Those are two discovery routes to one person, not permission to create duplicate biographies and split the SEO history.
The YouTube tracker should list `1tW8WqXumNk` as Jiwoo’s official solo audio while ARrC videos remain on the group hub and connect here only when he participated. That separation keeps group totals honest and makes the solo start visible rather than buried beneath later ARrC uploads.
My bottom line: Ziwoo did not disappear after a vague departure notice. Jiwoo returned with a verified label, release date, official artist upload and writing credit. The profile’s job is to hold the boundary around private reasons while following the public music accurately. Anything less would turn respect for privacy into neglect of the career that continued.

The writing credit changes the solo reading
Jiwoo shares lyric credit on “STAY IN THE MIRROR” with Woosoo. That does not prove every line is autobiographical or reveal which writer supplied which phrase. It does establish that Jiwoo participated in building the song’s language rather than only arriving to sing a completed brief.
The official album description frames the track around love, anxiety, self-questioning and becoming a light inside darkness. Those themes connect naturally to a mirror image without requiring fans to read the ARrC departure into every word. A new artist deserves the right to release a song that is not a coded press conference about his old company.
Production credits keep the collaboration visible: Woosoo and Solshine composed, Solshine arranged, and 5SECONDS COMPANY released the record. One-person branding still rests on a team. Accurate credits make the solo identity stronger because they show what Jiwoo specifically contributed.
Why the official audio belongs in the tracker
The YouTube upload is on Jiwoo’s Official Artist Channel and is provided through 5SECONDS COMPANY and ADA. That is sufficient official evidence even though it is audio rather than a narrative music video. The tracker follows exact official releases, not only expensive visuals.
Its video ID is `1tW8WqXumNk`. This page embeds that exact upload once and links it in the artist trail. A future MV, live clip or performance version would require its own exact relationship rather than silently replacing this record.
The playlist audit’s ARrC React requirement remains separate. “STAY IN THE MIRROR” is not currently one of the two ARrC `awesome` playlist slots; it belongs to Jiwoo’s artist history. The distinction prevents the complete-playlist metric from swallowing releases the user may want to add later.
From group main vocalist to solo center
In ARrC, Ziwoo’s voice supplied contrast around several members’ rap, dance and visual responsibilities. Solo work removes that scaffolding. Jiwoo must create the opening identity, sustain the middle and make the final return feel earned with one vocal character at the center.
That shift rewards restraint. The song’s emotional pop/R&B frame leaves room for smaller changes in onset, breath and vowel shape. A singer who tries to prove freedom by belting over every bar would rebuild the same crowded problem in a different format.
The debut is one data point. It shows direction, authorship and willingness to return; it does not settle the full range of Jiwoo’s future catalog. The page will track development release by release rather than declaring a mature signature sound from one single and its instrumental.
Privacy and continuity can coexist
Respecting ‘personal reasons’ does not require freezing the profile at departure. The boundary covers what Ziwoo did not disclose. His later label, official song, credits and artist channel are public career facts and should be followed with the same care as any other release.
That balance rejects two bad archives: one invents a scandal to explain the exit, while the other becomes so afraid of intrusion that it ignores the verified comeback. Jiwoo deserves neither gossip nor disappearance.
My bottom line: the correct record is original ARrC main vocalist Ziwoo, departure announced January 22, 2025, then solo artist Jiwoo with a March 13, 2026 co-written debut. One person, one canonical page, two accurately labeled phases and no fan-fiction bridge between them.
Jiwoo’s archive standard
Future Jiwoo updates need exact credits, dates and official uploads. A second single could confirm the introspective direction or reject it completely; either outcome is more useful than treating “STAY IN THE MIRROR” as a permanent personality diagnosis.
The profile will also keep names searchable. Ziwoo connects the ARrC archive, while Jiwoo identifies the 2026 solo phase. Both route to the same canonical URL so fans, search engines and card directories do not split one career into competing biographies.
The return is meaningful because it is documented, not because it retroactively explains the departure. Jiwoo can move forward without turning private history into promotional fuel. That boundary is part of the record too.
The next audit should also watch whether the official artist channel consolidates future Jiwoo releases under the same identity. Distribution systems can create duplicate topic pages, split capitalization or separate audio from visual uploads. The site will route exact official IDs to one canonical profile rather than copying metadata errors into new biographies. That filing work is not glamorous, but it is how a one-song solo start becomes a searchable catalog instead of another former-member trail fans lose six months later.
