Nogizaka46 member Hori Miona will graduate from the group. 

On November 27, the music video for Hori's solo song "Tsumetai Mizu no Naka" was uploaded onto YouTube. The video starts with Hori talking about her feelings about being in the group, and ends with her graduation announcement. It was directed by Yamato Yuki who also directed Hori's first starring film 'Hot Gimmick: Girl Meets Boy.' 

Hori passed Nogizaka46's second generation audition in March of 2013, and was promoted to a regular member when she became the center for their single "Barette" released in October that year. She released her first solo photo book 'Kimirashisa' in November of 2017 and her second book 'Itsuka no Machiawase Basho' earlier this May.
