Lilith, the lovely maid, has recently been hired to cater to the whims of her employer's son, Yuuri. Yuuri's overzealous skepticism of her every action, on the other hand, keeps him on edge, as he suspects devious mischief is being planned behind his back. Despite his paranoia, Lilith grows fond of Yuuri and frequently teases him to strengthen their bond. In this day-to-day oddball romantic comedy, Saikin Yatotta Maid ga Ayashii revolves around the relationship between the cautious Yuuri and his wonderfully charming maid.
