I’ve Been Reincarnated as a Villainous Aristocrat Who Tries To Steal Women From the Protagonist in an Erotic Fantasy Novel, and I’m Trying To Live an Honest Life, but I Steals Every Single Woman From the Protagonist. Why!

One day, I was reborn in the world of the most popular fantasy novel in the world.
I was reborn not as the main character, but as Marcoy Draco, a villainous aristocrat who stands in the way of the main character.
Born into an elite family of dark wizards, Marcoy is destined to ultimately fall into darkness and ruin.
Knowing the ending of the original story, I don’t want to die, so I vow to live as a decent human being.
For now, I thought… to stay away from the hero, but I intercepts the hero’s events.
And take the heroines one after another.
Wait, wait, wait, I don’t want to do that!
I found out that my position and the hero’s were reversed… and the hero fell into the darkness!
This is a story about me, who was only an intruding character, who (as a result) takes everything away from the hero. Why!
