My Boyfriend, The Mad Dog(2010)

Kyoukenn・Kareshi

Honma, a remarkable freelance assistant, begins helping a popular mangaka, Akae, who’s arrogant, pompous, extremely sadistic and quickly wraps Honma around his little finger. On top of that, Akae really likes his assistant but seems like he’ll force him to do things that go beyond the call of duty! (Source: Jmanga)
