Seo Eun-kwang

Seo Eun-kwang (서은광) built his reputation on the kind of singing that makes brute-force technique sound easy. As the leader and main vocalist of BTOB, he anchored one of K-pop's strongest live vocal identities and turned emotional precision into the group's competitive edge rather than just a nice extra.

He debuted under Cube Entertainment in 2012, then spent the next decade expanding far beyond idol basics. Musical theater, variety, radio, and television hosting all widened his profile, while solo releases such as FoRest: Entrance, Last Light, and 2025 full-length UNFOLD gave him room to frame that voice outside group arrangements.

After BTOB's post-Cube reset, Eun-kwang moved into the member-led BTOB Company structure without losing momentum. That matters. He now reads less like a veteran surviving on goodwill and more like a still-active vocalist with one of the clearest authority curves in second-generation K-pop.

When did Seo Eun-kwang start his solo career?
Seo Eun-kwang formally launched his solo career in June 2020 with the mini album FoRest: Entrance. The release gave him a dedicated lane outside BTOB and showed how his voice could carry a full project on its own, not just as the emotional anchor inside a group arrangement.
What is Seo Eun-kwang's 2025 album UNFOLD?
UNFOLD is Seo Eun-kwang's first full-length solo album, released in 2025 through BTOB Company. It followed the single Last Light and pushed his solo catalog into a bigger, more mature frame, pairing the vocal strength fans already knew with a more complete album-scale identity.
What company is Seo Eun-kwang under now?
Seo Eun-kwang is currently under BTOB Company, the member-led label structure created after BTOB's departure from Cube Entertainment in late 2023. The move allowed him to continue both group and solo activity inside a setup built around the members rather than a legacy major-label contract.
Does Seo Eun-kwang work outside music?
Yes. Seo Eun-kwang has built a broad entertainment profile through musical theater, radio, and screen hosting. Credits like Monte Cristo and Weekly Idol matter because they show he is not only a vocalist but also a reliable all-round entertainer with range across live and broadcast formats.
