Ura Aka - L'Aventure

Fashion boutique manager Machiko (Takiuchi Kumi) creates a secret social media handle after her sales assistant makes an off-hand remark, and she starts posting racy photos. Machiko loves getting reactions unlike anything in her legit world, and she has a one-night stand with one of her followers, a younger guy who calls himself Yuto (Kamio Fuju).
