Seoul (서우)

The structured facts provided describe Seoul (서우), born Choi Hyungwook, a guitarist and producer and member of the group O.O.O — not Soyul of Crayon Pop, whose biographical data and recent coverage appear in the narrative material by error. The two are different artists, and the available material does not contain sufficient verified information about Seoul to support a profile beyond what the structured facts alone provide.

Based only on the confirmed structured data: Seoul is a South Korean musician, born May 22, 1992, who serves as guitarist and producer within the group O.O.O.

No further factual detail — discography, debut circumstances, chart performance, or broader career narrative — is present in the provided material. Publishing a profile beyond these confirmed points would require inventing content, which falls outside sourcing standards.

A profile of Seoul can be developed once supporting editorial material is available.
