Background and release

It was released a year and a half (560 days) after, "Shitsuren, Arigatō" and was marketed as the first single in which only AKB48 members participated since 2010's "Chance no Junban".^[2] The single was released in seven physical editions, comprising both regular and limited editions of Type A, Type B, and Type C, and a theater version.^[3] The single's release was first announced at the group's 15th anniversary on May 23, 2021 at Pia Arena MM.^[4] The groupmembers who would participate in the A-side track were announced on July 7, 2021.^[5]

This marked the last single for member Yui Yokoyama, the first single in which Hitomi Honda participated after returning from Iz*One,^[6] and the first single released after Minami Minegishi's graduation. Nana Okada returned to the center position for the first time since Jabaja in 2018.^[7]

"Nemohamo Rumor" was first performed on the TBS program "THE MUSIC DAY 2021" on July 17, 2021.^[8][9] During Yuki Kashiwagi's hiatus for health reasons, her choreography was performed by Erina Oda.^[10] The choreography is in a locking style and was choreographed by Jun Kandabashi, the dance teacher of the Mie High School dance club "Serious Flavor",^[11] who also appears in the music video.

B-sides

"Hanarete Ite mo" (離れていても; Even When We're Apart) was first released in 2020 as a charity single performed by all the group's current members and some of the notable graduates, but was later credited to the senbatsu members from the single Shitsuren, Arigatō and graduates only.^[12] Every active member in the group participated in either the A-side or one of the B-sides.^[13]
