Satou Mitsuru is an otaku who designs female game characters. His latest female design just so happens to look like a live-in male house keeper named Ninomae Nagisa. In order to see his character in the flesh, Mitsuru decides to have Nagisa as his new live-in house keeper!

Ninomae Nagisa is a young good looking guy. However, his cheeky appearance gives others the wrong impression. Even though his style is a bit flashy, he's a sweet guy and the first person to realize this and not judge him based on his looks was Mitsuru. Therefore, Nagisa decides to make Mitsuru his lover – no matter what it takes.
