Nogizaka46 member Renka Iwamoto, 20, has suspended her activities after private photos of her with a man surfaced online.
In a heartfelt apology, she vowed to reflect on her actions and prioritise Nogizaka46, saying, "Nogizaka46 is more important to me than anything else. I am truly sorry."
Management has yet to decide the length of her suspension, though she will miss a January 26 event.
Former Nogizaka46 members Ikoma Rina and Hori Miona drew mixed reactions for their playful online exchange regarding the issue on Twitter/X.
Ikoma Rina joked about pixelated images on Rentan's apology letter, and Hori Miona chimed in with laughter.
While some fans appreciated their humour, others criticised the pair for insensitivity during a challenging time for Renka.
The incident has sparked debate on the pressures faced by idols and the support they need.
