Gyaru na Maid wa Zangyou Shitakunai!

Suddenly showing up at the protagonist's home was the popular girl from his class.

Her true identity? A housekeeper hired by his parents. In other words... a "maid."

Under the terms of their agreement, "maid duty ends at 7 PM"—
during work hours she's the perfect maid, but once the clock runs out, she turns into a classmate who gets a little too close...

Getting lost watching her clean,
having her plop down next to him on the couch to play games,
finding her sneaking into his futon because she's lonely...

Before he knows it, he's completely at the mercy of her "two faces."
