The story follows a rookie female detective, Hiyori, as she investigates suspicions of illegal activities at a women's massage parlor in Tokyo, teaming up with a senior colleague for an undercover operation. Amidst scenes of lewd acts between lesbians, Hiyori's diligent investigative attitude and beautiful naked body stand out. However, some viewers express a desire for pure lesbian interactions rather than convoluted plotlines and dramatic scenes, with particular appreciation for the authenticity felt in the final intimate moments.
