timelesz has announced that they will release a new double A-side single, titled "Zayuu no Mei / Honto no Koto wo Iu to," on February 3, 2027.

The single will mark the group's first CD release of 2027.

One of the title tracks, "Honto no Koto wo Iu to," will serve as the theme song for the upcoming film Oneechan no Midori-kun, starring member Masaki Hashimoto, which opens in theaters across Japan on December 4.

The song is a bittersweet love song about confronting one's true feelings despite inner struggles. It will be released digitally on November 25, ahead of the single's CD release.

The single will be available in four versions: Limited Edition A, Limited Edition B, Regular Edition, and Fan Club Limited Edition.

Limited Editions A and B will include a Blu-ray or DVD featuring the music videos and behind-the-scenes footage for "Zayuu no Mei" and "Honto no Koto wo Iu to," respectively. The Regular Edition will feature a reversible cover and two additional tracks not included on the limited editions.
