Seo Kyoungbae

Korean main vocalist and youngest member whose self-taught beginnings became part of the PROJECT 7 story and the vocal foundation of CLOSE YOUR EYES.

Profile

Before CLOSE YOUR EYES

Born in Gyeryong, South Korea. Entirely self-taught in singing and dance before PROJECT 7. Practiced in his bedroom, earning the nickname Room Idol.

Why Seo Kyoungbae matters to the lineup

Seo Kyoungbae entered the group with a different amount and kind of experience than the other six members. That unevenness is part of CLOSE YOUR EYES’ appeal. The lineup joins veterans, survival-show returnees, trained performers and members who were nearly self-taught. Main Vocalist is the official label. The more useful question is how that role changes once the group’s choreography, vocal blend and live stages start moving.

Fandom notes

• Fourth-dan taekwondo practitioner
• Former volleyball player and Haikyuu fan
• Finished PROJECT 7 inside the seven-member debut lineup.
• Debuted with CLOSE YOUR EYES in April 2025 through the mini album ETERNALT.

Formation and debut

Seo Kyoungbae entered PROJECT 7 without the long agency-training history common to many survival-show contestants. His self-directed practice made his progression through the program especially important to the final lineup narrative. He earned a place in the seven-member CLOSE YOUR EYES team, which officially debuted on April 2, 2025 with the mini album ETERNALT. That release is the start of his professional discography and the correct baseline for his years active.

Performance identity

As main vocalist and the group’s youngest member, Kyoungbae carries both musical and developmental expectations. His profile is best understood by tracking how his tone, stability and confidence change across official recordings and live stages. His taekwondo and volleyball background add context for stamina and coordination, but they do not replace evidence from the music itself. CVM Sekai classifies this one canonical page as a current Member profile. He does not receive Artist-directory placement unless a formally credited solo music career begins.

Seo Kyoungbae entered with the shortest runway

Kyoungbae was widely introduced as a largely self-taught contestant who practiced singing and dance outside a long agency system. He then finished PROJECT 7 in fourth place and debuted as the youngest member of CLOSE YOUR EYES. The compressed timeline is the point: he went from bedroom practice and survival-show evaluation to professional recording, music shows and touring while still in his teens.

The “Room Idol” story is charming, but it can become a trap if it replaces analysis. Self-taught does not mean magically complete. It means his early habits were built without the same daily correction other trainees received. Group rehearsals then had to refine technique without sanding away the directness that made voters respond to him. His development should be tracked in breath, pitch, stamina and confidence—not in sentimental speeches about natural talent.

Why the vocal role matters

Kyoungbae is commonly identified as a central vocalist in the lineup. His tone gives CLOSE YOUR EYES enough melodic stability to attempt softer material such as “All My Poetry” without hiding every exposed phrase under production. On harder songs, the challenge changes: he has to keep that clarity while choreography and heavier percussion compete for breath. Live stages are where the difference between a pretty recording color and a dependable group voice becomes measurable.

Maknae without turning him into a mascot

He is the youngest member, born September 29, 2008, but “maknae” is a relationship inside a team, not a complete personality. Taekwondo and volleyball details help explain physical coordination; they do not tell us how he thinks. The page should give him the dignity of a working performer whose decisions and skills will become clearer over time, not reduce him to the child everybody else feeds on camera.

RaeRae take: Kyoungbae’s origin story sounds like the internet invented a vocalist in a bedroom and mailed him to a survival show. The real achievement is less magical and more impressive: he kept learning fast enough that the professionals around him could build on what he taught himself.

The catalog this profile now has to cover

Within that release sequence, Seo Kyoungbae needs to be measured after debut rather than kept inside PROJECT 7 forever. CLOSE YOUR EYES did not spend its first year parked beside one debut single. ETERNALT arrived on April 2, 2025 with “All My Poetry” and a softer literary identity. Snowy Summer followed in July, then blackout in November pushed the group into darker R&B and club production through “X” and the Imanbek collaboration “SOB.” The April 2026 digital single “POSE” widened the performance language again. Those releases are the professional timeline for every member page; competition footage explains the route in, but the group catalog shows the artist after debut.

The short project window makes every documented step in Seo Kyoungbae’s growth more valuable. The speed matters because CLOSE YOUR EYES is a project group. Three years sounds generous until album preparation, touring, health breaks, travel and ordinary human exhaustion start eating the calendar. Each comeback therefore needs to do two jobs at once: deliver a song now and leave enough evidence to show what this member has learned since the last one. A profile that freezes everybody at PROJECT 7 is not a profile. It is an audition recap wearing newer clothes.

What the official profile confirms—and what it does not

Because no rigid position chart exists, Seo Kyoungbae’s role has to be described from repeated work rather than fan shorthand. The official Japanese profile confirms the seven-member lineup, the PROJECT 7 origin, the April 2025 debut and each member’s birth date. It does not publish a rigid position chart. Position labels elsewhere on this page are therefore treated as working descriptions drawn from credited parts, stages and established secondary profiles, not eternal corporate law. K-pop positions move as songs change, voices develop and choreography gives different members the center.

For Seo Kyoungbae, evidence protects both against inflated praise and against a debut-era ceiling. That distinction protects the member from two equally lazy readings. One is inflating every idol into a main-vocalist-main-dancer-secret-producer. The other is deciding a debut-era label is a ceiling. The useful evidence is official music, full-stage cameras, album credits, interviews and dated company notices. The profile can have an opinion, but the receipt and the opinion should never be smuggled into the same sentence.

How this member fits the seven-person machine

Seo Kyoungbae’s part in that chemistry is visible only when the seven-member map remains intact. Jeon Minwook supplies veteran judgment and leadership; Ma Jingxiang gives the formations scale and a powerful international voting history; Jang Yeojun brings accumulated trainee and broadcast experience; Kim Sungmin embodies the most visible growth curve; Song Seungho connects rap and vocal passages; Kenshin carries instinctive performance appeal; and Seo Kyoungbae gives the lineup an unusually young vocal reference point. The chemistry works because those jobs overlap without becoming identical.

The better question for Seo Kyoungbae is what happens to the group around him when the camera is elsewhere. That relationship map is more useful than ranking the members from “most talented” to “why is he here.” Survival programs already spent months turning people into scoreboards. The group stage asks a different question: who makes the person beside him more convincing? Watch the spacing, the handoffs between vocal and rap lines, and who keeps energy alive when the camera is pointed elsewhere. That is where a project lineup becomes a group.

Current status: August 2026

Seo Kyoungbae remains part of the verified seven-member lineup at this checkpoint. As of August 27, 2026, all seven members remain active in CLOSE YOUR EYES. UNCORE announced on August 10 that the group was preparing a new album with a late-September comeback as the goal. The album title and final release details were not yet part of that announcement, so this page records the plan without pretending a scheduled target is already a released era. “POSE” remains the most recent released group single in this profile until the comeback actually arrives.

Seo Kyoungbae’s next update belongs in the career narrative as soon as the release becomes official. This checkpoint also prevents a common directory failure: a page can look polished while quietly ending a year behind the artist. Current status belongs near the career narrative, not hidden in a spreadsheet note. When the September release becomes official, its title, credits, video and member-specific evidence should be added here and to the group tracker together.

The one-video React connection

The exact “SOB” relationship gives Seo Kyoungbae one verifiable performance record instead of a fuzzy title match. CVM Sekai currently has one exact official-video relationship for this group: the 2025 Korea Grand Music Awards mega-crew performance of “SOB” with Imanbek. The site’s Iconic by Mistake deep dive is linked by the exact YouTube ID uf_5eKmzXYk. That relationship belongs on the group hub and every member profile because it is group work, not a random related card.

For Seo Kyoungbae, video-ID discipline prevents a stage, music video and dance file from being merged by accident. One correct relationship is better than five fuzzy ones. Future Reacts should be added only when the reviewed upload and the tracker share the same official video ID. A title match is not enough when performance videos, music videos, dance versions and awards stages can all carry nearly identical names.

Source discipline and update rule

Seo Kyoungbae’s source trail uses official records first and secondary databases only as cross-checks. Primary sources establish the official lineup, release dates, notices, credited work and current promotions. Korean entertainment reporting supplies translated interview context and dated agency statements. Fan databases can help locate a detail, but they are cross-checks rather than permission to copy a rumor into a biography. Height, MBTI and hobby lists are especially prone to surviving long after the original source disappears.

The same rule keeps Seo Kyoungbae on one canonical page as the career expands. The update rule is simple: change the page when the artist does something documentable. A comeback adds the release and its specific contribution. A health notice gets dates and neutral language. A solo credit can add Artist-directory classification to this same canonical person page. None of those events justify inventing a duplicate profile or deleting the earlier career that explains how the member arrived here.

Release-by-release watch guide

ETERNALT: establish the baseline

Start with “All My Poetry” and the April 2025 debut stages. The softer arrangement leaves fewer places to hide timing, tone and facial control behind an aggressive beat. For Seo Kyoungbae, watch vocal stability under movement and the refinement of skills first built through self-directed practice. The debut is not the final verdict; it is the cleanest baseline for measuring what changes later.

Snowy Summer: test range without abandoning softness

The useful replay question for Seo Kyoungbae is how the expression changes without erasing the performer underneath it. The July comeback kept the group melodic while making the visual world stranger and brighter. “Snowy Summer,” “Paint Candy” and the related stage material show whether a member can adjust expression and energy without becoming a completely different performer every era. This is where the group began separating adaptability from costume changes.

blackout: increase the pressure

“X” and “SOB” ask for sharper attack, darker confidence and more rhythmic weight. Compare the full-stage footage with the debut rather than comparing thumbnail views. Seo Kyoungbae is especially useful to watch here as the youngest member whose development cannot be reduced to a maknae mascot edit. The question is not who owned the era on social media. It is whether the member made the arrangement and formation more convincing.

“POSE” and the 2026 turn

Seo Kyoungbae’s choices during “POSE” matter more than another generic claim that the whole group matured. The April 2026 single arrived after the group had already cycled through three mini albums in one year. By then rookie novelty was no longer enough. The performance had to show choice: where to hold back, when to hit, and how to keep seven people distinct without turning the stage into seven separate auditions. That maturity is the bridge into the announced late-September comeback.

How international fans can actually follow the work

Seo Kyoungbae’s record is especially easy to fragment when schedules and clips travel across different language feeds. CLOSE YOUR EYES has official Korean group accounts, Weverse, an official YouTube channel and a Japanese fan-club site. International fans still have to assemble the story from multiple places: Korean comeback notices may appear before translated summaries, Japanese schedules live on a separate site, personal posts can be mistaken for official announcements, and short-form clips often circulate without the release date or original upload attached.

To verify Seo Kyoungbae, the official upload and dated notice remain the starting point. The safest route is to begin with the official YouTube channel for music and performance video, use Weverse and the group’s official social accounts for schedule notices, then use the Japanese site for Japan-specific activities. Translation accounts are helpful alerts, not primary evidence. If a post does not link back to a company notice, official account, album credit or complete interview, treat it as a lead to verify rather than a fact to repeat.

The point of Seo Kyoungbae’s canonical page is to remove that scavenger hunt without turning rumor into biography. This page helps by keeping dates, aliases, group relationships and exact video IDs together. It does not scrape every airport photograph into a timeline. The goal is a career record a reader can follow from outside Korea without needing six apps, three fan wars and a detective board made of red string.

What the next comeback needs to answer

• Does the September record continue the darker blackout/“POSE” lane, return to the literary softness of ETERNALT, or find a bridge between them?
• Where does Seo Kyoungbae receive a specific musical or performance responsibility rather than generic screen time?
• Are there official lyric, composition, choreography or production credits to add?
• Does the official-video upload receive an exact React relationship, and do the group/member trackers point to the same ID?
• Does the release change the working role description on this page, or merely give better evidence for the role already described?

Editorial bottom line

Seo Kyoungbae belongs in the CLOSE YOUR EYES member directory as a current member from 2025 to the present. The page is deliberately one canonical biography: survival-show history, pre-debut work, group releases, later credits and future solo activity all stay attached to the same person. A new era should deepen this record, not spawn a second profile with a slightly different spelling.

RaeRae bottom line: Seo Kyoungbae does not need a puff-piece crown. The useful case is already onstage: vocal stability under movement and the refinement of skills first built through self-directed practice. The September update should be judged by receipts—live vocal evidence, credited music work and how the next record protects his tone in heavier production—not by whichever ten-second clip wins the algorithm that week.
