Hotaru's Way Vol. 2 (Kodansha, 2017)

Somehow or another, Hotaru's hitting it off with her younger boyfriend, Makoto Teshima. But as the holiday season approaches, sure enough, her himono ways threaten to sabotage their relationship…and that's not even getting into her roommate and manager, Takano-buchou, who's suddenly awfully friendly with her! The age of the spinster might be over, but the Himono Age is only getting started!
