Singer Yoon San-ha of boy band Astro will release his third solo EP “No Reason” on May 20, his agency Fantagio said Tuesday.

“No Reason” marks the singer’s first solo release in 10 months since his second EP “Chameleon” came out in July last year.


The title of the lead track, “IDK Me,” was also unveiled Tuesday through an image of a scheduler released the same day.

The singer will also release two versions of concept photos — “Undefined” and “Unbound” — along with the album’s track list and a highlight medley at later dates, according to the scheduler.

Preorders for the EP will open at 2 p.m. on Wednesday.

Yoon debuted as a member of Astro in 2016. The four-member group — MJ, Jinjin, Cha Eun-woo and Yoon — has released songs such as “Crazy Sexy Cool” (2017), “Baby” (2017), “After Midnight” (2021) and “Candy Sugar Pop” (2022).

Yoon launched his solo career in 2024 with the EP “Dusk.”

The singer also held the concert tour “Prism: from Y to A” across 10 cities last year.
