Uchi no Tenshi ga Kemono Deshita.

Descripción general

Satou, Mitsuru is an otaku who designs female game characters. His latest female design just so happens to look like the 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. Even if that means turning from an angel into a beast! Mitsuru keeps rejecting Nagisa, but how can he resist someone who looks so much like his beloved angel like character he designed! (Source: LuffyNoTomo)
