I Reincarnated as Earnest, But This World’s Morals Are Broken

A mentally weak middle-aged man who cannot refuse women when asked “do it” finds himself swap-reincarnated with a boy in a medieval fantasy world. In this new realm, slavery, polygamy, and might-makes-right are the norm. Using his modern knowledge and past experiences (including sexual), he begins to stand out. However, by modern Earth standards, his actions are those of a scumbag. The catch? He remains completely unaware of this fact. This is the story of a man who thinks he is serious and earnest, while inadvertently becoming a villain in the eyes of morality—a tale of war, politics, and harem building in a world where ethics are fluid. — Description from novelcodex.orgFull novel: I Reincarnated as Earnest, But This World’s Morals Are Broken — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
