Title says it all, I know this is somewhere on the site bit I couldn't find it before. No harem, romance is fine, preferbly something that doesn't get boring. Thanks.
Gotta ask how it is not harem when. Spoiler MC sleeps around with a bunch of women through out the story. Upon breaking the bloodline shackles he makes both his mistress and his wife pregnant, along with a ton of other women that are never revealed who they are. It is only mentioned in the same chapter as we get to know he has just impregnated his wife that he has "rewarded" a bunch of other females in the clan with his seed and that he can feel the new lives growing, which he finds as a strange sensation. Later on he kidnaps two more females and keeps them as his mistresses and if I remember correctly forcibly impregnates them to carry his children, however they both bear daughters and only the two sons from his wife and first mistress is given any real screen time in the story. So while for most of the story the harem members isn't given a lot of screen time it is kind of hard to deny harem when at least the 2-4 "main" harem members are given quite a few chapters of screen time. To name some Dungeon Defense (it could be argued that the MC is more insane then evil and that his evil is justified by his end goal, this is probably one of my favorite novels on here, also even though it has a harem tag I would give it a try, short spoiler Spoiler The MC has one lover in the story so far, and except for that is forced into a F-buddy relationship by someone much stronger then the MC, except for that there is nothing that would point at the MC having a harem so far. ) Katahane no Riku (Female protag I've not read it myself yet heard the MC is pretty dark and evil) Youjo Senki (Same as above used to get a ton of recommendations but not so much after the translation was stopped pretty much after vol 1.) Renegade Immortal (It's about a devil cultivator and him pretty much killing and pillaging resources across a bunch of different world.) Seoul Station’s Necromancer
I still need this, help me out. It would be great if it was entertaining as well, leaving you on the edge of your seat
WMW MC isn't really EVIL. He's more just ruthless, and out for himself before anyone else. I'd call him more cold and callous than evil.
