Villain System: City of Eternal Night

[ Warning: Mature content R-18 ] "A law-abiding man gradually transformed into a villain simply because he kept a promise to his mother. Any woman who crossed his path would become a part of his harem." This is a primarily slice-of-life novel, and the pacing will be relatively leisurely. ____________________ ***Warning*** There is no NTR/Yuri Although MC won't be NTR'd, he will treat others like this.
