FC Machida Zelvia
On September 20, it was announced that member Mio is pregnant, would marry soccer player Cayman Togashi (FC Machida Zelvia) and thus would retire from the entertainment industry within the rest of the year. After talks between the Flower members and the staff of LDH in light of Mio's retirement, it was decided that the group would disband at the end of the same month. The other former Flower members would start their solo careers managed by LDH. On September 30, all Flower members posted messages on their personal Instagram accounts, thanking their fans and the other members, promising their continuing support for each other and showing excitement for their future. On October 1, the group's social media accounts were deleted and its official profile was removed from LDH's website.
