He is back after more than ten months.
Last Monday, May 4, Korean music label Fantagio announced that ASTRO member Yoon Sanha will be dropping his newest mini-album later in the month.
Entitled No Reason, it will mark his solo comeback after dropping Chameleon back in July 2025, which carried the song Extra Virgin.
So far, the company has confirmed that the release date will be on May 20, with concept teaser photos and videos already being unveiled one by one as that date approaches.
Sanha made his debut as the youngest of the six original members of K-pop group ASTRO in February 2016.
The group is known for their songs like Hide&Seek, Breathless, Confession, Baby, Crazy, Sexy, Cool, All Night, Knock, ONE, and Candy Sugar Pop, among others.
In 2020, he also became one-half of the sub-unit Moonbin&Sanha with late fellow member Moonbin. Under the unit, they released tracks like Bad Idea, WHO, and Madness.
Sanha is also active as an actor and had been part of projects like Love Formula 11M, Your Playlist, Crazy Love, and Romance In The House.
In August 2025, he also visited Manila as part of his Prism: From Y To A fan-con tour.
