Villain's transmigration: Breaking every heroine into a Yandere Novel

[WARNING: EXTREMELY MATURE CONTENT AHEAD. READ AT YOUR OWN RISK.]***After three years of writing a novel without success, with just a single reader, Alex decided to end his novel forcibly. But the moment he released his last chapter, the scene before him shifted from a dark, gloomy room to a vibrant one filled with decorations.Before he could do anything, he was faced with the truth that he had been transmigrated into the very novel he had just finished, not as the protagonist, nor as an extra, but as the most hated villain of his novel... Noah Von Asthor. The notorious troublemaking son of the Duchess.Now he not only has to figure out how to survive as the villain who is hated by all, but he also has to change the end he made if he does not wish to perish by his own hands (and also make a harem, that's a must.)***The mc here is a true villain, don't expect him to be just a guy pretending to be one, he is evil to the core, and will literally break the heroines, as well as other villainess or anyone he likes, both physically and mentally until they are obsessed with him, no matter which path he has to take. And yes, he Will love them all as well. So if you are weak hearted, then don't read it, I don't want anyone whining in the comments later.This thing contains the blend of plot and “plot” in the ratio of 4:6 and you can expect anything in this one but don't expect outright sex just after a character is introduced, and if you wish for additional tags then,Netori, Large harem, Yandere, Milfs, Win-cest, Virgins, Elves, Beasts, Spirits, Demons, Dragons, Queens, Princess, Kinks, Master-servant relations, student-teacher relations, Extremely Perverted protagonist, Smart MC, degenerate MC/author/readers.[P.S.: Brothers in arms, if we are going to hell, we will go together.]https://discord.gg/ZxdTxN6jgT
