Yoon Sanha will release his third solo mini-album, "NO REASON," on the 20th.

On the afternoon of the 4th, Yoon Sanha revealed a scheduler image announcing the release of his third mini-album, "NO REASON," through his official SNS. The image caught attention with a photo of Yoon Sanha standing against a red curtain, clipped onto a file holder design.

According to the scheduler, starting with the mood sampler release on the 5th, various teaser contents will be sequentially unveiled until the comeback, including concept photos in UNDEFINED and UNBOUND versions, the tracklist, highlight medley, after scheduler, and two teasers for the title track "IDK ME." The title track "IDK ME," an abbreviation for "I don't know me," hints at Yoon Sanha's new charm showcased in this album.

Pre-orders for the physical album will begin at 2 PM on the 6th at various music stores. Yoon Sanha is making his solo comeback after about 10 months.

Previously, Yoon Sanha continued his activities as a solo artist by releasing his first mini-album "DUSK" in August 2024 and his second mini-album "CHAMELEON" in July 2025. Each album included self-composed songs "Fox Star" and "AURA."

Additionally, last year he successfully completed the fan-con tour "PRISM : from Y to A" in 10 cities across Asia and Latin America, and this year, for the third consecutive year, he has actively performed birthday commemorative small theater shows linked with his own music content "SANiGHT" in Korea and Japan.
