Stage name: Seoho. Birth name: Lee Seoho. Birthday: June 7, 1996. Current group: ONEUS. Current company operation: B.Wave. Status: active. ONEUS debuted under RBW on January 9, 2019 with LIGHT US and “Valkyrie.” The group began with six members; Ravn departed on October 27, 2022, and the continuing lineup became Seoho, Leedo, Keonhee, Hwanwoong and Xion. All five ended their exclusive RBW contracts in February 2026 while retaining the ONEUS name and transferred the group IP operation to B.Wave. Seoho completed active-duty military service on August 16, 2026, reopening full five-member activity.

Before debut

ONEUS did not arrive as six anonymous faces. Training projects, evaluation programs and public stages created uneven amounts of pre-debut footage. This file uses that record as context without forcing Seoho to remain the person an edited competition introduced.

Debut and the six-member catalog

LIGHT US and “Valkyrie” establish the professional starting line. Ravn’s later departure does not delete the original recordings. Seoho belongs to both the six-member history and the current five-member group, with the transition dated rather than blurred.

Performance identity

Seoho is the main vocalist with a bright, athletic upper register. The useful evidence is how that quality changes across LIT, LUNA, Same Scent, Baila Conmigo, X and Grenade. A fixed position can identify responsibility; it cannot replace listening to breath, phrasing, rhythm and handoffs.

The five-member era

After October 2022, ONEUS continued as Seoho, Leedo, Keonhee, Hwanwoong and Xion. The group re-recorded selected earlier songs as Penta versions, making the change audible and explicitly labeled instead of pretending only one master chronology exists.

The company transition

All five members ended exclusive RBW contracts in February 2026 while preserving the group name. Official notices later identified B.Wave in the IP and service transition. Seoho therefore continues one ONEUS career across companies, not a newly debuted identity.

Seoho’s service window

Seoho entered active-duty military service and completed it honorably on August 16, 2026. “X,” Grenade and Under document the group’s activity around that service window. His return changes current status, not the participant list in those exact videos.

Artist routing rule

Seoho has verified individual original work within the official ONEUS release ecosystem, so this same canonical page can serve both member and Artist discovery. A second biography would split dates, images and credits for one person.

X and the exact React

The “X” React follows exact official upload 7tEgWyYB8YE. It links Seoho only where participation is visible or otherwise confirmed. Seoho remains part of the group chronology but is not inserted into a four-member MV relationship merely because he returned later.

International fan guide

Use official ONEUS, Japanese-site and agency notices first. Company transfers often leave old handles, copyright lines and storefront pages active at different speeds. The page preserves dates and sources so international fans can follow the transition without treating every stale footer as a new scandal.

RaeRae take

The interesting part of Seoho is not a superlative. It is the way a recognizable choice survives changes in concept, lineup and company. ONEUS concepts are loud enough to hide a person who only performs the mood board; Seoho is worth tracking when the decision remains identifiable underneath it.

What to watch next

The first full five-member work after Seoho’s discharge should clarify updated line balance, credits and live arrangement. This page will add exact releases and verified status changes without cloning the human into separate member and Artist files.
